NO ASSISTANCE
What does that rule mean? For Conrad it meant taking a mooring without using his
engine, and tantilisingly close to ‘normal life’, but not permitted in any way
to be helped by anyone, no items allowed to be received on board, no physical
contact with the outside world. These are the tough rules of the Vendée Globe,
no assistance means no assistance.
AUTOPILOT:
Electronic steering system that steers KINGFISHER by reading the wind angle from
the anenometer at the top of the mast, and the compass heading. In fast-building
wind conditions the delay between the anometer reading the wind strength at the
top of the mast to relaying that information to the autopilot can cause delayed
reaction.
CATERING ON BOARD
Like all top level sports people, sailors must be careful about their diet. But
crews have to cope with constricting parameters. On board, stowage space is
limited and too much weight of stores would be detrimental to the yacht's
performance. As for the food itself, it must be able to be conserved for long
periods and provide a minimum energy intake. There's no question either of
having a whole set of pots and pans and matching dinner service. The most common
solution is resorting to powdered food (freeze dried or dehydrated), made up
into menus developed by nutritionists. Energy bars and beverages complete this
Spartan diet. Sometimes the skippers decide to take on board "real" food (in
cans, all the sameŠ), a bad decision for the payload, but good for the morale.
It's a way of ensuring that the boat's performance doesn't suffer too much and
that everybody is happy.
A CHINESE GYBE
is the description sailors give to a particular spectacular, and potentially
dangerous wipeout when the boat careers out of control and gybes by
accident...the mainsail smacks across, but with the top part of the sail still
on the previous gybe...complicated to show without a picture, but even more
complicated to get out of! As the french say...bordelle...total mess!
CONVERGENCE ZONE
The water temperatures of the Southern Ocean are far from uniform. Around 60
degrees South, where the Southern ocean meets the warmer southward flowing
waters of the Atlantic, Pacific and Indian oceans, is the zone known as the
Antarctic Convergence, or Polar Front. The total area of sea within the
convergence makes up one tenth of all the world's oceans, and contains the
coolest and densest water to be found anywhere. The effect of this is to create
the area of most icebergs that break off the ice shelf. For more information, go
to http://www.doc.ic.ac.uk/~kpt/terraquest/va/science/geography/geography.html
‘Crash box’
all the Open 60s have sacrificial bow sections so that if they hit something the
first bit to break is a foam core half metre section that absorbs some of the
shock. This bit can actually break off completely without damaging the
structural integrity of the boat. The boats have at least 6 watertight
compartments as well, so it takes a serious amount of damage to cause a major
safety problem. Of course any damage is not good for performance, and a
collision with an iceberg growler cannot do great things for the mental state of
the skipper....
ILES CROZET: The 20 small mountainous islands of Crozet are a French
territory and are uninhabited except for scientific personnel and penguins. Home
to seals, King Penguins and other birds, Crozet is designated a national
conservation area by France. The mostly barren island is subject to low
temperatures and long winters. The island climate is mitigated somewhat by
maritime influences. The inland plateaus are barren and rocky. Steep cliffs drop
to sealevel on the coasts. First landing was in 1772, with the first settlers,
Sealers arriving in 1804.
CYCLONE
Eine "Cyclone" ist ein tropischer Sturm der schleudert wie ein Wirbelwind Die
unteren Lufpartien der Atmosphäre werden in größere Höhen gesaugt. Sobald sich
eine Cyclone formiert hat verbreitet sie sich mit dem Kopf - mit absorbierender
Feuchtigkeit auf der Oberfläche des Ozeans. Der Wind kann 250 km/h erreichen ...
In nördlicher Hemisphäre sind die Cyclon Saisons zwischen July und November. Im
Oktober während des Transat. Jacques Vabre mit Yves Parlier, Ellen MacArthur
hatte die Cyclone Irene zu bewältigen mit Wind Exzessen bis zu 55kn (102km/h).
Während der EDS Atlantic Challenge wir die Flotte wahrscheinlich nicht so weit
südl. Kurs segeln um in ein derartiges Phänomen zu gelangen. Sie müssen immer
ein Auge auf tropische Tiefs haben - die Geburtsstätte dieser Stürme in denen
die Winde wirklich unzuverlässig sind.
DAGGERBOARD
Daggerboards are an essential part of an Open 60
setup when sailing upwind - with a swing keel, the daggerboard acts as lateral
resistance. Kingfisher's daggerboards are assymetric, almost 4 metres long and
weight over 70 kgs - necessary to take the excessive loads put on them when
sailing upwind. The board was designed such that in the case of an impact like
this it should break first, rather than break the boat - an important success
from a design point of view. They were also designed to be used in an emergency
the other way up - like now, although not without a fair bit of work to make it
possible. Likewise, the damage to the tip of the rudder was controlled by the
sacrificial part at the bottom of the blade. It is structurally sound and with a
very small performance effect.
Daggerboards are used to improve upwind performance - like a centreboard on a
dinghy, they help prevent the boat from being pushed sideways off their proposed
course. When the boat is sailing upwind the daggerboard is lowered under the
boat . There is a port and starboard daggerboard positioned approximately
one-third back from the bow, and depending on which tack the boat is on ie port
or starboard, the appropriate board is lowered into the water.
Distance to finish
measurement that the leaderboard is based on, is worked out on the basis of a
theoretical course, the shortest possible within practical limits. Of course due
to the wind and sea the boats can never steer this minimum distance, as they are
always tacking, gybing or heading around weather systems to make the best speed
towards the finish possible – rarely can they sail in a straight line. The
theoretical course for the Vendee Globe is 23,700 miles, so Nick has just
crossed that half way mark, but will probably still have 13 to 14,000 miles left
to sail, rather than just the 11,850 theoretical ones. BUT he’s on the second
half of the race, which is good for moral onboard!
Doldrums/The Trade Winds
A few degrees north of the Equator, there is an area known technically as the
Inter-Tropical Convergence Zone (ITCZ). In very basic terms its where the North
East Trade winds and the South East trade winds meet each other...effectively
cancelling each other out as the result is air moving more vertically than
horizontally – vertical air makes for a suction effect resulting in either no
wind or often violent rain squalls. In the old days sailing ships might be stuck
for weeks in the Doldrums...these days, it can be race losing or winning, but
the light and powerful Open 60s can accelerate so quickly that they can use each
squall to get themselves across relatively quickly – albeit with large amounts
of sweat and frustration on the way...
The Trade Winds are split into two areas – the Northern Trade Wind sector (N/NE
winds) start along the coast of Portugal to the Equator; then the Southern Trade
Winds (S/SE winds) after the area of the Doldrums – a notorious windless zone: "You
hope to find some good Trade Wind sailing whilst working on the best position to
cross the Doldrums. You need to gain as much westing as you can to cross this
area as this is normally the best position to be in. Although, contrary to that
in the last TJV the guys to the east actually benefited more than the guys who
were further west. Crossing the Doldrums you enter into upwind sailing then you
are looking at reaching and downwind sailing."
Downwind:
Sailing with the wind coming from behind the yacht. If ASHFIELD HEALTHCARE is
pointing south, to sail downwind the breeze has to come from a northwest, north
or north east direction. The mainsail will be at 80 degrees to the centreline of
the boat and the yacht may carry a spinnaker [large balloon type sail] at the
front to catch as much wind as possible.
ENTERTAINMENT ONBOARD?
As Nick mentions today, he does have the ability to watch DVDs via the Sony VIAO
laptops that form the nerve centre of SKANDIA’s nav centre. He is also a Sony
sound system, a few books and a lot of manuals if he really gets bored! He also
has a bunch of DV tapes that his friends and team recorded for him before he
left...the reality is though it is very rare in a 3 month round the world race
that the conditions allow the skipper more than a 5 minute diversion from
tactics, trimming, maintenance (body and boat), sail changes, weather, eating,
sleeping...
EPIRB:
- Emergency Position Indicating Radio Beacon : these transmit on 406 MHz, the
international distress frequency. The McMurdo precision EPIRBs onboard
KINGFISHER can be manually activated or automatically due to full immersion in
water. McMurdo Pains & Wessex are a Performance Partner of Team Kingfisher
Figaro Solo
Die Figaro Bénéteau ist ein 9.14 m (30 ft) Einrumpfer mit einem Tiefgang von
1,80m (5,9 ft). Sie in Frankreich bekannt als gebräuchlich im "Solitaire". -
eines der Rennen, das zur French Figaro Meisterschaft gezählt wird - wie das
Transat AG2R und das Porquerolles. Jedes Jahr im August gehen ungefähr 30 dieser
Boote als eine Klasse an den Start. (die Teilnehmer haben alle identische Boote)
für ein Einhandrennen in 4 Stufen - entlang der Westküste Europas. Die
hauptsächlichst besuchten Länder sind : Frankreich, Irland und Spanien.
Gestaltet 1970 von Eugène Dautriche unter dem Namen des "Course de l'Aurore",
wurde die Solitaire von Pascal Bidégorry in Europ Assistance gewonnen.
"FLYING A HULL"
KINGFISHER2 is a catamaran - she has two hulls. When fully cranked up in
moderate to strong breeze, it is possible to sail with the whole 22 tons of boat
balancing on just one of the hulls - this means less drag in the water, and so
usually is accompanied by a big increase in speed...but it also means that the
boat is that much closer to the point of no return. If the hull is to come out
too far, the bit will basically tip over (capsize) something which is terminal!
It's a balance between pushing for the extra speed and saving the boat, crew and
whole project! The boat right now is quite light - once 65 days of food, fuel
and spares are added, she could be as much as 1.5 tons heavier so at the start
of the trip, one would expect the boat to be pushed less hard, preserving her
for the long long challenge around the planet...
Fog
Considerably reducing visibility, fog is dreaded just as much at sea as on land.
Formed by droplets of water in suspension in the air, fog is in effect a cloud
in contact with the ground. With a high rate of relative humidity when the
temperature falls, the water of the ground or the sea evaporates and the water
vapour condenses, forming a white mass that we call fog when the visibility
falls below 1 km, and mist when it is between 1 and 5 km. At sea, this lack of
visibility can prove to be dangerous in areas of heavy shipping or in the high
latitudes where icebergs may be present. This is why boats are equipped with
radar for detecting an object on the water within a radius of several kilometres.
Contrary to fog on land that dissipates as the sun comes up, fog at sea
disappears when the wind changes direction and pushes the cloud towards warmer
waters.
Gale
40 knots of wind is a force 9 gale. 50 knots of wind is a force 11 gale. Either
way its bloody windy! Enough to lift your dog of the pavement....
Gefriergetrocknete Speisen an Bord
Für die Segler, die am EDS Atlantic Challenge teilnehmen, ist
Gefriergetrocknetes Essen wichtig für den Sieg. Dieses Essen ist Vakuum verpackt
und maximal konserviert. Es reduziert das Gewicht an Bord der 60 Füßer und hilft
die Geschwindigkeit zu erhöhen und spart eine gute Menge Platz ein. Jeden Tag
nehmen die Herausforderer, die Top Sportsleute sind, zusätzlich dieses
exzellente, kalorienhaltige Supplement zu sich - zu ihrer Basis Diät von Pasta
und Reis. Der Gefriertrocknungs-Prozeß nimmt etwas Aroma von den Speisen. Es
beinhaltet auch alle essenziellen Nährstoff-Qualitäten. Nimm als Beispiel eine
gefriergetrocknete Paella. Ein 100 g Päckchen hat eine Nährmenge von 1621 kJ und
382 kcal. Das Mal zuzubereiten kostet auch weniger Zeit : Alles was du tun mußt
ist, der Menge entsprechend heißes oder kaltes Wasser hinzuzufügen und schon
hast du deine Gemüse- Salat - oder Pilzsuppe. Die Gegenseite: dieses Essen ist
wie auch immer, sehr teuer.
DIFFERENCE BETWEEN A GENNAKER AND A SPINNAKER ?
When the wind is coming from between 100 degrees true (ie 100 degrees back from
the bow, direction of travel) and dead behind, the Open 60s deploy sails known
as either Spinnakers or Gennakers. The difference has become less obvious with
developments in recent years of a number of different designs – but a spinnaker
tends to be made from a nylon type material and is very full, used for when the
wind is aft of 140 degrees, and a set of different sized and shaped (flatter and
smaller area) gennakers for a wind further forward. Gennakers are usually made
from stronger materials, and furl around their headstay (the cable that supports
the front edge, known as the luff), rather than the spinnakers which are
‘snuffed’ with a sock that pulls down over them. Changing between these sails is
a technical and often exhausting operation...with plenty of margin for error, as
the skipper balances on the foredeck of his boat as it continues to surf down
the waves...
Great circle route.
The great circle route is the shortest distance between two points on the
surface of the Earth. As a general rule, a straight line is the shortest
distance between two points on a flat surfaceŠ But this rule doesn't apply to
the Earth which is "round". Therefore at sea, sailors must take into account
several factors to reach their "waypoint" or destination. The speed of the boat,
the changes in the weather, the currents, the direction of the wind, and so onŠ
just some of the parameters that help sailors adapt their tactics. For the fifth
leg of the EDS Atlantic Challenge for example, the 60 footers like Kingfisher
use the Gulf Stream, a warm current, like a natural "conveyor belt" to EuropeŠ
To do this, they first had to descend down south away from the direct route.
GROWLERS:
More dangerous in many ways than the giant icebergs that drift north from
Antarctica, are the smaller chunks that break away from the main bergs. Even
large icebergs are hard to see on radar as they are partly transparent, the
small chunks you only ever see at the last minute...but they are hard enough and
big enough to put a hole in a carbon fibre boat traveling at 15 knots towards
it. The growlers often drift further north before melting away...a constant
danger for the Vendée sailors regardless of the ice gates that have kept the
fleet further north than in the past.
GULF STREAM
The Gulf Stream is a warm ocean current. It starts out in the gulf of Mexico
before heading north up the coast of America. Afterwards, in a clockwise
direction, it heads over to Europe before splitting into two parts, one of which
head north towards Europe and the other towards the coast of Africa. For the
crews taking part in the EDS Atlantic Challenge, negotiating this current is a
highly strategic affair. The boats which opted to go north, as Kingfisher did,
decided to sail along the coast where the current is much weaker. But there is
an element of risk in terms of tactics with this option : should the winds turn
out to be lacking, the boats would be "sucked up" by the Gulf Stream and would
find themselves stuck in place. AS things have turned out, this strategy seems
to be paying off since the boats are sailing at very similar speeds, at an
average of around 10 knots.
GYBE :
just as when a boat zig zags either side of the wind when its going against it,
when the boats sail with the wind behind they do not sail directly in the
direction of the wind. Instead they sail with the wind at about 150 degrees from
their heading, in order to generate some ‘Apparent Wind’ of their own. They then
must ‘gybe’ back and forth to get to their destination. The actual manoeuvre
involves turning the boat so the stern moves through the wind, the sails come
crashing (sometimes) across to the other side of the boat, and the boat heads
off in the other gybe with the wind on the other side of the boat. A gybe for
the solo sailor, in any kind of breeze, is a dangerous manoeuvre, but they have
no choice! The worst case is an accidental gybe under autopilot...
DIFFERENCE BETWEEN A ‘GYBE’ AND ‘TACK’?
A gybe is when the boat’s stern (back end) is turned through the wind, so the
wind passes from one side of the stern to the other. The mainsail bangs across
as the wind catches the other side of the sail. A ‘tack’ is when the bow is
passed through the wind, so it is more gentle and controllable as the sails flap
from 30 degrees either side of the wind, the boat slows until the sails fill
with the wind on the other side. When it is really windy, a ‘gybe’ can be a very
difficult and dangerous manoeuvre, and so sometimes a skipper will instead
decide to round up and trying and tack instead – the problem being the sudden
increase in apparent wind as he turns in to the wind requiring a reduction in
sail, and then less speed to manouevre. Not easy out there!
GYBING
When a boat sails with the wind it is very slow to sail directly with it –
instead a raceboat will zig zag, doing the manouevre of a ‘gybe’, keeping the
wind at 140 to 150 degrees true angle to the direction of travel. This way the
boat will also create additional ‘apparent’ wind, and therefore the boat will go
faster, and overall even though sailing further will make better speed towards
the objective (known as VMG, Velocity Made Good). The ‘gybe’ itself, is the
manoeuvre, often tricky and dangerous in high winds, of passing the sails from
one side to the other as the wind pass through the stern from one quarter to the
other. More on that one later!
Headwinds
To reach a point [land or waypoint at sea] that is directly in front of the
yacht and where the wind is coming from, yachts must sail against 'headwinds'.
Health on board
It's not easy coming back from a week at sea without some knocks and bruises.
It's no surprise to anybody: the sea is never still! And keeping one's balance
on a boat thrown around by the waves is sometimes more akin to a bout of boxing.
From a simple bruise to a fracture, knocks are frequent and the faster the boat,
the more they are violent. It's a struggle against gravity, but also against the
cold and damp. Wrapped up in a foul-weather suit, a sailor might be warm, but
one sweats. And the rubbing of clothes on damp skin causes irritation, even
boils. Another enemy is the lack of sleep. Whether single-handed or as a crew,
the sailor rarely sleeps comfortably and for long enough. Even if they are used
to this sort of out of phase rhythm, certain people can find it difficult
recuperating, notably because of the stress, the cold and the noise. Then put on
top of that an inadequate diet and it's seasickness guaranteedŠ Even for
professional sailors!
History of multihulls
While the first multihulls were imagined by the Polynesians hundreds of years
ago, the ancestor of current day multihulls dates from 1877. Designed by Nat
Herreschoff, this revolutionary catamaran had a centreboard and a rudder on each
of its hulls, and a central pod, and was capable already of reaching a speed of
18 knots. In 1947, Manu Kai, the first modern multihull, saw the light of day,
and the 50s saw an explosion of dinghies and small beach cats in plastic. The
trimaran, with its three hulls made a comeback in 1968 with Pen Duick IV. But
multihulls didn't steal the scene until 1984, with Elf II and the start of the "carbon"
era. Today, the no-limits race called simply The Race gave birth to a new era of
giant multihulls of over 30 metres long capable of reaching incredible speeds (the
record going to Innovation Explorer with 42.2 knots) and going round the world
non-stop in 62 days (winner of the race: Club Med).
HOTTER ANGLE
If you imagine running in the same direction and at the same speed as the wind,
you would not feel any wind on you at all. The 'Apparent' Wind would be zero. If
you are on a boat at that time, there would be no pressure on the sails and you
would slow down. If at that time you headed left 30 degrees, you would start to
feel apparent wind on you, and you would go faster. That is sailing a 'hotter
angle', it's a choice between going where you want to go slowly, or heading up
in to the wind and going faster!
IMOCA
IMOCA, the International Monohull Open 50/60 Class Association is one of the
organisers of the EDS Atlantic Challenge. It gained official ISAF recognition as
an international class in 1998, bringing together the best skippers in the world
and is headed by Christophe Auguin. It was created with a view to increasing
safety on the 60 foot Open monos during great ocean races like the Vendée Globe
or the Around Alone. One of the main requirements is the self-righting capacity
of the boats. The next ocean race for the class will be the two-handed Transat
Jacques Vabre after which the IMOCA World Champion will be named.
JUMARS:
are the climbing apparatus to scale the 27 metre mast - classical mountain kit,
they allow you to clamp a hand grip device on to a rope, pull up on it, then
release it to slide it further up (or down) the rope. Critical support for the
solo sailor when they are forced to scale the towering carbon fibre masts.
Knot:
Boat speed is measured in knots. 1 knot = 1.1515 miles/hr exactly. 1 nautical
mile = 1.151 land mile. 40 knots of wind = 46 miles per hour. Now If you have
ever stuck your head out of the sun roof going along at 40 miles per hour -
that's windy - do it when it's raining and you might get some idea of what its
like for the skippers! (Not that we are advising this.)
‘LAZYJACKS’
are the lines that a rigged on either side of the mainsail, between the boom and
a point about one third up the mast. They are adjustable, and are used to hold
the boom up off the deck and coachroof when the sail is not fully powered up (in
which case the shape of the sail essentially holds the boom up on its own). Last
night Nick had the mainsail all the way down, and when the boat was rolled the
force of the water on the boom and stacked mainsail will have easily been enough
to break them. In fact the jammer that they are secured with ripped off the boom
rather than the lines breaking themselves, so Nick was able to temporarily
re-tension the lazyjacks and secure the line on the winch at the mast.
‘LIFT’ and ‘HEAD’
When a sailor says the wind is ‘lifting’ it means it is moving further behind
him, when it ‘heads’ him, the wind comes from a direction closer to the bow.
When you are sailing with the wind from right behind, ‘downwind’, then a wind
that heads can be helpful, as the boat goes faster on the same heading as the
apparent wind increases. Downwind, ‘a ‘lift’ is bad news therefore due to less
apparent wind.
When you are sailing against the wind, ‘upwind’, a ‘header’ is bad news, forcing
you to bear away and sail further from the course you want. And a ‘lift’ upwind
is of course a bonus!
Lizard-Ushant Line
Dies ist die gedachte Linie zwischen Lizard Point in Südengland und dem
Leuchtturm der Insel Ushant in der Bretagne. Sie bezeichnet die Start- und
Ziellinie für Weltumsegelungen und andere Hochseerennen. Für Rekordfahrten wird
wegen der Kontrolle durch den WSSR meist The Lizard als Zielpunkt angesteuert.
Kartenskizze
Manouvres
Manoeuvring at sea, whether it's on a monohull or a multihull is similar: it's a
question of hoisting and dropping sails, taking reefs (to reduce the surface of
the mainsail), tacking (changing from having the wind on one side to the other -
starboard-right or port-left - by turning through the wind), gybing (changing
from having the wind from one side to the other by turning downwind), etcŠ The
big difference is that the trimaran is more powerful and faster. So man¦uvres
are more violent: "multihulls are more stable.
Meridians - On the globe, lines of constant longitude
extend from pole to pole, like the segment boundaries on a peeled orange. Every
meridian must cross the equator. Since the equator is a circle, we can divide
it--like any circle--into 360 degrees, and the longitude angle of a point is
then the marked value of that division where its meridian meets the equator.
What that value is depends of course on where we begin to count--on where zero
longitude is. For historical reasons, the meridian passing the old Royal
Astronomical Observatory in Greenwich, England, is the one chosen as zero
longitude.
"Minis 6.50" Class
In the beginning, the "Mini" class was intended to encourage ocean racing on
small low cost monohull yachts measuring 6.50 m (21,32 ft) long. Today, the Mini
6.50s are veritable scale models of 60 ft (18.28 m) Opens like Kingfisher. There
are two types of Minis: the prototypes and production minis, from the famous "Muscadet"
in 1963 and the "Coco" in 1984 both designed by Philippe Harlé, to the "Super
Calin" designed this year by Jean-Pierre Magnan. To be recognised as a
production Mini by the class, ten strictly identical examples of the boat must
have been built. The main technical characteristics: A "Mini 6.50" is 6.50 m
long, as its name suggests, has a draught of 2 metres, a mainsail of 32 m_, a
solent jib of 11 m_ and a medium asymmetric spinnaker of 70 m_, among others.
Monohull to Trimaran
Apart from their length (60 ft or 18.28 metres), the trimaran Foncia-Kingfisher
and the monohull Kingfisher don't have much in common. The former is almost as
wide as she is long with 17.50 metres from one outrigger float to the other,
whilst Kingfisher has a beam of only 5.40 metres. As for weight, it's quite
surprising, even though the monohull is smaller than the multihull, she is
heavier, weighing in at 8.5 tonnes compared with 5.5 tonnes for
Foncia-Kingfisher. Why? Simply because of the ballast, or keel if you like, that
the monohull needs to maintain its stability in the water. A stability that the
multihull has naturally with her three hulls.
MRCC?
The world’s oceans are divided in to a number of regions that are monitored and
controled in terms of maritime safety by different countries and co-ordination
centres. In the time of a crisis, it is the MRCC that manages all the rescue
actions and recieves the emergency position signals.
Navigation. Calculating one's position
Making a sailing boat go is one thing, but taking it to a precise point by
following a chart is another. To know where one is going or where one is, and
before the invention of electronic aids and the GPS (Global Positioning System)
which with satellites enables one to obtain instantaneously and precisely a
position in latitude and longitude, sailors determined where they were with the
help of landmarks along the coast (lighthouses, windmills, belfries and towers,
etcŠ), but also with the help of the sun and the stars when they were sailing
offshore. That's what we call celestial navigation. For this they used a sextant,
an instrument that enabled them to measure the height of a star from the horizon
and calculate their position. Today, many skippers take a sextant with them,
because if they have an electronics failure, it becomes an indispensable piece
of equipment.
Navigation (cont'd). The heading and the course.
Once he knows his position on the chart, the sailor can determine what heading
to follow to arrive at the desired point. For this he uses a protractor or chart
plotter (there are various sorts, like the Cras, the Breton, the Portland or the
square protractor). But the heading on the chart (true heading) is not quite the
heading to follow because you must take into account leeway (or drift) and the
currents. So the navigator does some variation calculations in function with the
strength and direction of the currents to give the helmsman a "compass heading".
From this, the crew can estimate the time needed to complete the course
depending on the point of sailing and the speed of the boat, and also depending
on the strength of the wind and the state of the sea, in other words, the
weather.
PBO is a hi-tech fibrem
which can carry incredible loads of many tons, yet weighs virtually nothing.
Traditionally racing yachts have used metal rod rigging to hold the masts in
place and absorb the associated loads. Kevlar, Spectra, Vectran and PBO are all
different materials that have been introduced in the past decade to reduce
weight, improve reliability and make the boats go faster! PBO in particular is
now also used in racing car applications in Formula 1 for the same reasons...
PITCHPOLE:
when the bow or bows of the boat are ploughed into the wave in front by the
force of the wind - the bows dig in and the force of the boat being stopped in
its tracks causes the boat to capsize stern over bow.
Pitstops
– what is alllowed in the rules? The boats may anchor or moor as close to land
as they wish, but the skippers must not go ashore above the high water mark, and
must receive no outside assistance, or physical contact with other people.
Port tack
- when wind is on the left side of the boat going upwind and mainsail is on
right side of boat. Upwind sailing is position the boat as close as possible to
the direction of the wind without pointing into the wind (because you’d stop...).
To go in a direction against the wind, the boat must tack (between port and
starboard) in a zig zag fashion.
Punktwertung
Im EDS Atlantic Challange hat jede Teilstrecke die selbe Anzahl von Punkten. Das
ist eine Verbindlichkeit für dir Sprints (wie zwischen St. Malo und Cuxhaven:
575 Meilen) - und für die Transatlantic:3430 Meilen zwischen Porthmouth
(England) und Baltimore (USA). Nach jeder Teilstrecke werden die Punkte wie
folgt verteilt: 15 Punkte für den Gewinner, 14 Punkte für den zweiten, 13 Punkte
für den dritten Platz usw. Das ist nicht bei allen Veranstaltungen so: Einige
Rennen laufen in Etappen - wie die Solitaire du Figaro. Der Sieg wird nach
verstreichender Zeit gemessen - also, der Erste siegt und bekommt den Preis.
REEFING
The mainsail (the large one supported by mast and boom) can be 'reefed' to 5
different configurations, each one smaller than the previous. To 'put the first
reef in' means to lower the mainsail to the first reinforced line in the sail.
At either end of the sail there are eyes and ropes that can be hauled in from
the cockpit (using winch and pedestal) to 'reduce' the sail. When Ellen wants to
increase sail again as the wind drops, she releases these lines and then must
grind the sail up the mast again. Whilst the North 3DL sail onboard Kingfisher
is ultra-light technology, it is still comparable to hauling up a large fridge -
an exhausting exercise. To not reef when required as the wind changes, is to
either risk damaging the boat or sail at less than 100%.
Renn Yachten
Diese Woche, bei "Lernen und Verstehen" ist den Fähigkeiten von Renn Booten
gewidmet. Zum Beispiel: weiß du wirklich welche Bootstypen das EDS Atlantic
Challenge segeln ? Das sind 60 Fuß (18,28m) Offene Klasse - gebaut in
Carbonfiber um so leicht und schnell wie möglich zu sein
ROLE OF THE CREW
One race after another for Ellen MacArthur, but no two races are alike.
Single-handed during the Vendée Globe, crewed on the Challenge Mondial
Assistance and the EDS Atlantic Challenge, this yachtswoman sails every type of
race. On the Vendée, she had to be helmsman, trimmer, tactician, cookŠ and if
need be, mechanic. During the EDS, each member of the crew has his own role.
There are 5 people on board (2 English guys and 3 Australians), which makes
manoeuvring much easier and a much speedier affair altogether : helm, weather,
mast step, sails, trimming the main, the foresailŠ And according to Ellen "we
all get along perfectly well".
‘RUDDER’
Obviously the bit that steers the boat, Open 60s have two of them – unusually
for sailboats that normally have one. The reason is principally due to the very
wide shape of these boats, when they are heeling, if there was only one central
rudder it would come out of the water a considerable distance and so control
would be lost. Secondly to help the autopilots, two rudders are used one on each
side of the stern. When the boat is heeling the leeward rudder is completely in
the water, and the windward rudder usually completely out – and reverses when
you are the other tack. Therefore breaking one of these does not mean you have a
second spare one, as you need both...some boats have kick up rudders which flip
up under big loads, ie when they hit something, others have replacement rudders
(usually only one due to the weight) on the boat – this is the case of Joe
Seeten, but unfortunately he has already used his spare...fixing it is a
complicated job, usually done in a composite workshop with time and materials on
hand.
FLIP UP RUDDERS, WHAT ARE THEY?
Most of the newest generation Open 60s have flip-up rudders. All Open 60s have
two rudders (due to their width the windward rudder is often out of the water),
and the modern ones have configured them such that if they have a high speed
collision a fuse breaks, the rudder comes up out of the water rather than being
destroyed by the impact. A broken rudder could be race-ending.
Schiffs - Technologie
Die Technologie an Bord der Rennyachten sind fortschrittlich. Auf der EDS
Atlantic Challenge haben alle Scipper Instrumente an Bord die uns ihre
Verfassung wissen lassen. Sie können ständig mit ihren Sponsoren kommunizieren,
mit dem Land Team, der Presse, zusätzlich Videosequenzen, Fotos und Ton. Sie
können Wetterkarten einsehen - sie haben Internetzubehör. Während des Vandee
Globe - man erinnere sich - Ellen MacArthur hatte eine Webcam an Bord. Web-
Gebrauch gab eine Idee vom Leben an Bord Kingfisher. Die Technik ist dafür
gemacht, daß die ganze Welt dem Rennen lebensnah verfolgen kann.
Seegiganten
Im Januar 2001, Bruno Peyron lancierte das erste unbegrenzte Rennen um die Welt.
Aus diesem Anlaß bauten die Multiplast Werft in Vannes die Mehrrumpfschiffe CLUB
MED. Innovation Explorer und Team Adventure. Gilles Ollier, Marine Architekt,
träumte von diesen Riesen Katamaranen von 33,5 Metern (110 Fuß) lang mit 800 m_
(8611 fuß_) Der bekannte amerikanische Billionär Steve Fosset - mit seinem
Katamaran PLAY STATION ist auch an diesem Abenteuer beteiligt: Dieser
Mehrrunpfer war größer als drei andere (37,9m - 124 ft lang). Am Ende gewann
CLUB MED die Veranstaltung - gesegelt vom Neuseeländer Grant Dalton und dem
Franzosen Franck Proffit, und sie umrundeten den Globus in 62 Tagen 6 Stunden
und 56 Minuten - bei einem Schnitt von mehr als 18 Knoten !! Letztes Jahr am 22.
Juli, lancierte Olivier de Kersauson seinen Maxi-Trimaran. Dieser letzte
Meeresriese - Maß :34 Metern (111,5 ft) Länge - ist eine brechende Maschine von
Rekorden. de Kersauson will nicht weniger als 27 von ihnen angreifen.
Sicherheit an Bord eines 60 Fuß offenen Einrumpfers
Zunächst muß man einmal bedenken, daß die Fomel 1 der See. die 60 Fuß offene
Klasse der Einrumpfer Höchstgeschwindigkeiten von 30 kn erreichen - mit andern
Worten fast 56 km/h. Bei solchen Geschwindigkeiten ist kein Platz für Fehler.
Sicherheit an Bord ist oberstes Gebot. Die Renn Bestimmungen sind da um die
Sicherheitsbestimmungen zu definieren. Es ist wie bei ASIA. einer der
Mannschaftsmitglieder von AlphaGraphics, als sie Anfangs der dritten Etappe
außenbords fiel. Eine andere Anforderung : Eine Summe an Rechten an Bord: Jedes
Boot muß einen vollen Bestand an Überlebensgeräten an Bord haben.. Und zu guter
Letzt ein Element der Sicherheit, das man nie vergessen sollte, die
Verständigung auf den Booten zwischen Scipper und Crew .
Southern Ocean: Weather
Without any land masses to hinder them, the weather of the South is driven by a
series of low pressure systems that circle the bottom of the globe around
Antartica. The winds and wave heights can build to severe storms, and are
particularly unstable. The wind in the southern hemisphere rotates clockwise
around the systems (the inverse of the northern hemisphere), so being on the
northern side of them gives favourable downwind conditions as they travel east.
However, the further south you go the shorter the distance you sail. Finding the
compromise is the key decision to make...as well as trying to stay with the same
system for as long as possible - as you fall of the back of a depression, there
can be period of light winds while you wait for the next to catch you up.
Speed through the water
Why are multihulls quicker than monohulls? The answer is simple. Not having a
keel, they are lighter and have a much lower wetted area than monohulls. So they
suffer from less drag in the water and therefore go faster. In addition, their
three hulls give them form stability that allows them to increase their sail
area. They are more powerful and capable of creating their own apparent wind for
propelling themselves. In this way, the maximum speed of a 60 ft trimaran can
reach 36 knots (67 kph) whilst that of a 60 ft monohull tops out at 28 knots (52
kph). "It's much tougher", said Ellen MacArthur after the start of the Challenge
Mondial Assistance. "At the start we were going very fast, 26 knots!"
More wind doesn’t mean more speed...
Nick’s average speed overnight was not far from the outright 24 hour record
average, and he didn’t have more than 30 knots of wind for most of it. In 40 to
50 knots of wind in a big storm, like the leaders have been seeing recently,
they are not going any faster. These Open 60 boats are so powerful, they don’t
need much wind to get them going at max speed, and in fact as the wind continues
to increase the rough seas force the skippers to throttle bag to try and help
the autopilots keep the boats on their feet and avoid the big wipeout. Large
breaking waves are the really dangerous part. Trying to stay on deck and hand
steer the boats is virtually impossible for anything other than a few minutes,
as Nick in just 30 knots has described this morning...
HOW DO YOU SAIL FASTER THAN THE WIND!?
With modern high performance sailing boats, the power to weight ratio is such
that they are able to sail faster than the wind in many conditions – essentially
they create so much apparent wind of their own (see previous Jargon Buster!),
that they can easily attain speeds in excess of the true wind speed. Man has
learnt a lot about how to harness the wind since the days of the Clipper Ships –
which weren’t actually that slow though of course! Boats are becoming lighter
and faster with each iteration of design and material advances.
No wind
The French have a word for it; "pétole", or "molle"Š in Anglo-Saxon circles one
talks about "Harry Flatters". All these terms mean the same nightmare for the
sailor: no wind, and a sea like a mill pond. Once the yacht is "parked" (the
French say "Scotché" in tribute to the famous brand of sticky tape), such a whim
of the weather leaves few options. One can always resort to the "iron topsail" (engine)
or one can break out the paddles. But by a stroke of misfortune, if it happens
during a race, the only option open is to be extremely patient and limit the
damage as much as possible, like not going backwards for instance with the
current. If the depth of water allows, one can allows anchor and wait for Aeolus
(the wind god) to wake up. Contrary to popular belief, such a situation is not a
good time to catch up on rest either; the noise of the sails beating back and
forth and the creak of the boom swinging from side to side is generally most
unpleasant and annoying. You can't drop your guard either because the slightest
zephyr could enable the yacht to make precious headway and escape from her
competitors. The crew must permanently trim and re-trim the sails ready to
capture the slightest tremor of air.

STARTING RACES
In general, the starting line is laid perpendicular to the wind, so that the
yachts start to windward. This ensures lower speeds, therefore greater interest
in terms of strategy. Another important criterion is visibility and that the
public should be able to understand what is going on. The starting point is
usually in line with a landmark (for example a lighthouse). If this is not
possible, a mark at sea is used: i.e. the race committee boat on one side and a
buoy or another boat on the other side. Five to ten minutes before the starting
gun a warning signal is displayed in the form of a flag. Then comes the
preparatory signal (code flag 'P'). The boats start to head for the line in
order to cross it at full speed. Finally comes the starting signal itself. All
the preceding flags are lowered, and a gun is fired. They're off!
‘STORM FORCE’
Beaufort Scale terms are often misused. The word ‘Storm’ and ‘Gale’ have actual
definitions in terms of wind strengths in knots [nautical miles per hour].
Invented by Admiral Francis Beaufort in 1806, it was adopted by the Royal Navy
from 1838 and remains largely unchanged ever since... BEAUFORT SCALE for the
definitions!
Straße von Dover
Die Straße von Dover ist ein strategischer Punkt des Rennens. Sie trennt den
Englischen Kanal von der Nordsee und England von Frankreich. Sie formt einen
engen Flaschenhals von 30 km Breite den 250 Boote (Frachter, Tanker und Bulk
Carriers...) jeden Tag passieren. Nicht mitgezählt - die 90 täglichen
Fährüberquerungen. Man braucht nicht zu erwähnen, daß navigieren hier schwierig
ist. Erst recht für die Boote des EDS Atlantic Challange. Die Schiffe der Marine
folgen sehr präzisen Routen - genannt "LANES" - und sie weichen von diesen nicht
ab. Für Yachten sind diese "Lanes" nicht bindend und sie sind frei in ihren
Bewegungen. Aber beim Hin und Her zwischen den Frachtern verbleibt ein
schwieriger und ermüdender Sport.
TACKING - a special art onboard the Open 60s
Tacking (turning the bow of the boat through the wind) these boats is something
quite special in breeze like this weekend. A normal raceboat may tack through
the wind in just seconds - but onboard KINGFISHER we must first swap the
assymetric dagger boards over (these give the boat lift, since there is no keel
to stop her going sideways once it is swung right up to windward). Then we must
dump the keel to the minute (it is hydraulic), tack as normal, and bring the
keel back up - pumps working hard for a few minutes. Then lift out the old
dagger board. It requires a lot of co-ordination, and good timing on the tacks.
But its fun! Especially when the competition are behind....
Tiden
In ihrer Erdumlaufbahn üben Mond und Sonne große Kräfte von Anziehungskraft aus
die Auswirkungen auf die Erde haben. Diese Anziehungskraft zwischen den
Himmelskörpern provoziert das Phänomen der Tiden auf unserem Planeten. Im Punkt
der größten Anziehungskraft der Erde sind die Tiden am höchsten und umgekehrt am
niedrigsten. Zu der Energie der Anziehungskraft kommt die Zentrifugalkraft der
Erde die sich um ihre eigene Achse dreht. Auf der anderen Seite findet man im
Punkte der größten Anziehungskraft die höchste Zentrifugalkraft und somit hohe
Tide. Die Distanz des Mondes zu uns ändert die Anziehungskraft; das ändert die
Höhe der Tide (höchste Tiden nennt man Spring Tiden - und die niedrigsten Nipp
Tiden ) Der Hafen von Saint Malo', wo die EDS Atlantic Challenge endet, ist die
Differenz zwischen hoher und niedriger Tide - Tidenhub genannt - einer der
größten in Europa: mehr als 12 Meter. Der Durchschnitt in der Welt beträgt 2
Meter.
Tiefsee-Graben
Ein Tiefsee-Graben ist eine schmale Bodenspalte mit häufig sehr engen, steilen
Wänden, die auf dem Meeresgrund zu finden ist. Diese Art von Unterwasser-Spalte
kann bis zu 2000 Meter tief sein. Der Druck ist in der Regel sehr hoch, 600 mal
stärker als der Druck beispielsweise auf dem trockenen Land. Trotzdem existieren
in diesen Tiefen Lebewesen. Bakterien und weiter oben auch Weichtiere und
Seewürmer sind dort zu finden. Diese Urformen des Lebens entwickeln sich und
überleben auf Grund der Erdwärme, die dort unten das Wasser erwärmt.
Tiefseespalten sind Verletzungen der Erdkruste, in die der Ozean ungehindert
eindringen kann - bis in die Eingeweide unseres Planeten.
Trade Winds:
- two bands of steady winds either side of the equator. In the northern
hemisphere they blow from the north east and in the southern hemisphere from the
south east. SILL will certainly touch these winds soon, but ECOVER and
KINGFISHER are following a fairly direct route and may not touch them for a few
more days yet.
TRANSATLANTIC RECORDS
6. Québec / Saint-Malo
Diese Herausforderung entstand 1984 and war die einzige Transatlantik, die nach
von Westen nach Osten gesegelt wurde. Noch etwas, was sie unterschied von den
anderen, ist der erste Teil des Rennens ist den Saint-Laurent River hinunter.
Wale, Baumstämme auf der Wasseroberfläche. Nicht die kapriziösen Strömungen auf
diesem Wasserweg zu vergessen die das Rennen aufmischten. Der erste Rekord
dieses Rennens hielt Loic Caradec auf Royale. Er segelte 2897 Meilen (5365km) in
8d 19h 57'. Das nächste Rennen - 1988 - (es wird alle 4 Jahre gesegelt), Serge
Madec stellte diese Zeit ein: sein Katamaran Jet Services V gewann in 7d 21h 35'
44'' :Dieser Rekord stand bis 1996 als er von Loick Peyron (Fujicolor II)
eingestellt wurde. Er hält diesen Rekord bis heute: 7d 20h 24' 43''. In der 2000
Ausgabe muß nur ein Rekord eingestellt werden. 4 Teilnehmer müssen mehr als 600
Meilen in nur 24 Stunden zurücklegen ....
5. La Route du Café
The Transat Jacques Vabre was created in 1993, along a route inspired from the
coffee trade routes which go back to the XVIIIth century. The race starts out of
Le Havre (Normandy), finishes in Carthagena (Colombia) and is held every two
years. The first edition of the race was sailed single-handed. Paul Vatine raced
to victory on his multihull Haute Normandie II in 16 days 00h 46'. The monohull
benchmark time was set by Yves Parlier (Cacolac d'Aquitaine) in 18 days 23 h
38'. In 1995, the concept was fine-tuned. Objective : to become the longest of
all transatlantic races. From then on, the race was sailed two-handed. The
multihull record to be beaten is that of Laurent and Yvan Bourgnon (Primagaz)
set in 97 : 14 days 07h 37' 48''. The best monohull time is that of Thomas
Coville and Hervé Jan (Sodebo) in 1999, when they took 19 days 17h 31' 36''.
These records will never be improved upon, as this year, the course has been
changed. Whilst the boats will still set sail from Le Havre, they will be bound
for Bahia (Brazil).
4. Die Route du Rhum
Nach dem die Yachten der English Transat 1976 auf 60 Fuß (18,28m) begrenzt
waren, waren die Franzosen verärgert. Sie hatten drei der 5 Rennen und ihre
Boote waren für einen neuen Standart nicht tauglich. 1978 entschieden sie sich
eine neue Transat zu gestalten. In purem offenem Geist (keine Begrenzungen)
entlang dem Kurs einer klassischen Handelsroute. So lief die Route du Rhum
zwischen St. Malo (Brittany) und Pointe-à-Pitre (Guadeloupe, Französche West
Indien). Eben nach ihrer Einführung bot sich ein legendäres Duell zwischen dem
Französischen Scipper Michel Malinovski und dem Kanadier Mike Birch. Am Ende war
es der Kanadier der auf seinem kleinen Trimaran Olympus in 23d 6h 59' 35'' - nur
98 Sek. vor Kriter V - dem Verdränger des Franzosen. Der Rekord wurde alle 4
Jahre verbessert. Zuletzt wurde er 1998 von Laurent Bourgnon's auf Primagaz in
12 d 8h 41' '' gebrochen.
3. Das Englische Transat:
Entgegen zum ältesten Atlantik Kurs, der Rekord zwischen New York und Lizard -
der Englische Transatlantisch wird von Osten nach Westen gesegelt - zwischen
Plymouth (UK) und Newport (USA). Heute wird das in Europa als 1 New Man Star
(Einhand Transatlantik Rennen) . Es nennt sich so seit 1960. In dieser Zeit
brauchte der Gewinner (Sir Francis Chichester mit Gypsy Moth III) 40d 12h 30'
für dieses 2800 Meilen (5286km) Abenteuer. Seit dem wurde der Rekord viele Male
gebrochen. Die letzten Aufzählungen im Jahr 2000: Der Franzose Francis Joyon
setzte eine neue Richtlinienzeit von 9d 23h 54' 36'' auf seinem Trimaran Eure &
Loire. In der Einzelrumpf Klasse datiert der Rekord 1992 von Yves Parlier mit
Cacolac d'Aquitaine: 14d 16h. Die schnellste Frau ist immer noch Ellen MacArthur.
In 2000, Kingfisher nahm diesen Kurs in 14 d 23h 11'. Der selbe Kursrekord -
zweihändig - Laurent Bourgnon und Cam Lewis machten die schnellste Passage in 9d
8h 5' 20''
2. Cadiz / San Salvador
New York / The Lizard is not the only course of reference for setting
transatlantic records. In 1984, Spain decided to create a race on the model of
the route used by Christopher Columbus in 1492. At the time, it needed two
months for Columbus's caravels to sail from Cadiz to the West Indies. The first
edition of this Cadiz (Spain) / San Salvador (Bahamas) event set the initial
record: 12 days for Philippe Poupon on Fleury Michon VII. Four years later,
Serge Madec improved this time by nine hours on board Jet Services V. The holder
of the New York / The Lizard record did it in 12 days 12h 30' 17". This time
held until June 2000. Then Club Med skippered by Grant Dalton and Bruno Peyron "devoured"
the 3884 miles (7193 km) of the course in 10 days 14h 53' 44", or 45 hours
better than his predecessor.
1. New York - Lizard
75 Jahre - solange hielt Charlie Baar den Rekord der Atlantik Überquerung.1905
die Amerikaner an Bord der ATLANTIC - eine 56m (184ft) drei Mast Schoner -
erreichten Lizard Point (UK) in 12d 4h 1 ' und 19 ''. Ein Rekord, der bis 1980
stand, als Eric Tabarly den selben Kurs in 10d 15h 14' 22'' auf seinem Trimaran
PAUL RICARD schaffte. Dann folgten 10 Jahre Rekordwechsel mit sieben neuen
Rekorden. Der letzte von Särge Made mit JET SERVICES - ein 22, 85m(75ft)
Katamaran. ER überquerte den Atlantik in nur 6 Tagen 13h 3' 32 ''. Ein Rekord
der zu schlagen ist ...... morgen: Der Cadiz / San Salvador Rekord.
TRIMMING?
Not only are there a load of sail combinations to choose from, once a sail is up
there are a handful of small adjustments that can be made to the sail to
optimise its performance. Via a number of control lines and cable tensions, the
depth, fullness, shape, twist, flatness, angle to the wind can all be
changed...each little change can have an important impact on the speed of the
boat. And every tenth of a knot counts – 0.1 faster for 24 hours is 2.4 miles!
In some conditions the skippers will be able to leave the trim set for several
hours with the pilot steering to a wind angle, around this sail configuration.
Other times will require constant trimming to keep the boat at maximum speed,
even with the same sails set.
'Upwind' means the obvious...against the wind.
The next 4 to 5 days of the race are almost certainly to be on this point of
sail. It means the boat is fighting the wind, the sails are in tight, the boat
is heeling, the keel is canted to windward to try to keep the boat level, and
all the gear and weight is stacked to windward to get that extra hundredth of
knots of boatspeed.
From the Vendée Globe to the Challenge Mondial Assistance
The Vendée Globe and the Challenge Mondial Assistance are both non-stop ocean
races, and yet they are quite different in every way. The first consists in
sailing round the world starting from Les Sables d'Olonne (Vendée) and coming
back to the same port. In all some 26,000 nautical miles (48,000 km) on a
monohull (50 or 60 ft) and single-handed. In the Challenge Mondial Assistance,
the course is much shorter (2,700 miles / 5,000 km) and starts from Cherbourg
(France) to finish in Tarragona (Spain) via the Azores islands. And this one is
raced on 60 ft trimarans with full crews. Two different types of races and two
different types of sailing. The Vendée Globe requires above all good weather
tactics and plenty of endurance. The Challenge Mondial Assistance needs good
tactics and speed. So for a little over a week the crews of the multihulls will
be at the maximum of their possibilities. But in both races, the objective is
also to avoid breakages.
Verständigung mit der Außenwelt.
In der Mitte des Ozeans auf der EDS Atlantik Challenge sind die Seeleute nicht
von der Außenwelt abgeschlossen. Das An Bord Equipment ermöglicht es ihnen mit
denen an Land 24 Std. zu kommunizieren. Mit Inmarsat Telefon, Webcam, PC
angelehnt zum Internet.... Hinzu kommt zur Sicherheit - die Beobachter können
sich immer von den Geschehnissen an Bord überzeugen. Alle Mannschaften schreiben
tägliche Berichte die im Internet publiziert werden. Weiterhin, die täglichen
Chat Sessions, die denen an Land eine bessere Information über die Events an
Bord ermöglicht. Ellen ist die Einzige auf Kingfisher die diese Chat Sessions
macht : eine in französisch und eine in englisch.
Das Vorstag
Seit der EDS Atlantic Challenge, sind bei zwei Booten das Vorstag gebrochen:
Fila, sie ist aus dem Rennen und Sill Plein Fruit die die Fahrt fortsetzte,
nachdem sie etwas DIY an den Mastfuß getan haben. Dieses Drahtseil, daß vom
Vorsteven zur vorderen Mastkopf geht, hält den Mast vorne. Wenn das Drahtseil
bricht, ist die plötzliche Gefahr, daß der Mast runterbricht. Somit ist das
Vorstag ein sehr wichtiger Bestandteil wenn das Boot schnelle Fahrt machen soll.
Während des letzten Vendée Globe Challenge, hatte Ellen MacArthur sehr große
Angst als Ihr Vorstag brach - ein paar Meilen vorm Ziel - nachdem sie 23.000
Meilen non stop gesegelt war. Das hat sie aber nicht daran gehindert, das Rennen
zu beenden. Sie lief als Zweite in Les Sables d'Olonne ein.
‘Voyage for Madmen’
- check it out on Amazon, a book that must be read about the Golden Globe, the
forerunner to the Vendée Globe, and the first solo ‘race’ around the planet.
WATER BALLAST':
2 Vendée races ago (8 years) most of the boats in the fleet used water ballast
systems to give them their full righting moment - ie the power generated by
having weight to hold the boat upright as the wind pushes her over (from which,
via the aerodynamic effects of the sails, comes boat speed - in basic terms!).
Nowadays all new Open 60s use swing keels instead - the equivalent of having 30
people sitting up the windward side of the boat to keep her level! Water ballast
is still carried by the newer yachts, but primarily for trimming the bow down
when going upwind, and keeping the bow up when going downwind – plus a central
ballast for adding extra power (via weight) when reaching. Swing keels are
quicker to operate (push button hydraulics rather than pumping water around the
boat), but carry a small disadvantage of generally being heavier boats, because
unlike ballast boats, you can't empty the water/weight out when its light airs
and you don’t need it...
MANDATORY WAYPOINTS:
non-stop, solo, around the world...but a few marks to respect on the course,
designed to keep the boats further north and minimise (impossible to eradicate)
the risks of icebergs. The next waypoint for Nick is Heard Island, at 53 South,
72 East, which Nick must leave to to starboard, ie on his right hand side. After
that, there are two more waypoints to the south west and south east of Australia.
WEATHER MAPS
The weather maps show the isobars of atmospheric pressure, a (D) represents a
Depression (low pressure system), and an (A) an Anticyclone (high pressure
system). The small fleches indicate the wind strength and direction. The wind
direction is from the end of the line with the fleche to the other end of the
small line. The wind strength is 10 knots per full fleche (a half fleche
therefore being 5 knots). The weather 'fronts' are indicated - blue for cold
front, red for 'warm' front and purple for 'occluded' (when cold front has
caught up and merged with warm front). In the southern hemisphere, the wind
rotates in a clockwise direction around the Anticyclones, and anti-clockwise
around the Depressions. The reverse of what happens in the northern hemisphere.
WEATHER DATA BACK FROM THE BOAT:
the plan for a number of the boats was to communicate semi-real time data back
for the public to follow their race...hourly position, speeds, and weather data.
The race organisation made a new ruling just a couple of days before the start
that meant we were only allowed to send the weather element back...which we are
doing. How does it work? The data is collected by the onboard B&G instrument
system, recorded on Deckman software (5 minute averages) running on a Sony VAIO,
and then transmitted back to land via a small satellite unit called a Thrane &
Thrane MiniC. The data is then fed automatically in to the Active24 hosted
website...
Wettervorhersage und IT an Bord
Bei allen Ozean Rennen - wie das EDS Atlantic Challenge wurde die Informations
Technologie (IT) zu einem wichtigen, taktischen Werkzeug für optimale
Navigation. Der Navigator rüstet den Computer mit Wetterbehandlungsdaten für
größere, schnellere und mehr Erfolg für die Analyse. Ein Software Paket wie "Maxsea",
errechnet die Wettrervorhersage aus dem download vom Internet - und die
Geschwindigkeit oder die Position des Bootes. Auf diesem Wege kann die Route und
Position auch visuell auf der Seekarte erkannt werden. Der Navigator hat die
Möglichkeit seine Route auszuwählen und seine Strategie zu planen. Diese "routing"
software ist lediglich eine Hilfestellung für letzte Entscheidungen, weil die
kürzeste Route - berechnet vom Computer - nicht zwangsläufig die schnellste
ist..... Jeder Teilnehmer muß Vorhersagen und Trends voraussehen, was der
Computer nicht kann.
Weather in the Southern Ocean
Without any land masses to hinder them, the weather of the South is driven by a
series of low pressure systems that circle the bottom of the globe around
Antartica. The winds and wave heights can build to severe storms, and are
particularly unstable. The wind in the southern hemisphere rotates clockwise
around the systems (the inverse of the northern hemisphere), so being on the
northern side of them gives favourable downwind conditions as they travel east.
However, the further south you go the shorter the distance you sail. Finding the
compromise is the key decision to make...as well as trying to stay with the same
system for as long as possible - as you fall of the back of a depression, there
can be period of light winds while you wait for the next to catch you up.
WHY DOES A YACHT NEED WIND INSTRUMENTS?
Wind instruments are particularly important on a yacht like KINGFISHER2. The
sails are trimmed to an angle of attack to match where the wind is coming from
relative to the heading of the yacht. However, because the 'apparent' wind (which
depends on how fast you are going as this brings the apparent wind forward -
imagine running at 50km/h, the wind is in your face) is what matters in this
respect rather than the 'true' wind, on a multihull that is always travelling
very fast compared with the true wind speed the apparent wind changes very very
quickly. On a dark night, at speed, the B&G instruments can often be on the only
thing the helmsmen can see - and with his instincts and 'feel', the only way he
can keep the boat launching in a fast but safe direction as he weaves the boat
through the seaway. In such conditions with spray constantly blinding the
helmsman, to lose the instruments would be like blinding a Formula 1 driver half
way around the track...
WIND MODE':
modern autopilots, like the B&G ones on SKANDIA and many of the Vendée boats,
can operate in three modes. COMPASS, APPARENT WIND, and TRUE WIND.That means the
skipper sets the brains of the autopilot to steer to a fixed heading, a fixed 'apparent
angle' to the wind, or a fixed 'true angle' to the wind. In wind mode, the boat
will keep the heading at the same relative angle to the wind, hence the sails
should stay filled properly and the boat at close to maximum speed EVEN if the
wind changes direction. The downside if you are asleep is that if the wind
changes direction a lot, the boat will carry on sailing very happily, but
potentially in totally the wrong direction!
WIND WAND?
Solo sailors spend most of the time with their boats on autopilots. These pilots
are very sophisticated, taking inputs from gyro compasses and wind instruments
at the top of the mast, making very fast calculations to try and respond to the
changes in wind and waves and keep the 60 foot boats underneath their sails and
the boats heading in the right direction! Its a hell of technical challenge with
the boats surfing faster than the wind, down towering waves that can throw the
boat on its side very quickly. The pilot is the skippers’ best friend, or worst
enemy if its not working...Whilst the pilots can steer to a compass heading,
these boats accelerate so easily, therefore creating a rapidly changing wind
angle, that the boats cannot be pushed very hard using this basic mode. Instead
they are set to steer to a constant true wind angle. The key input therefore is
that of wind angle and wind speed. The ‘wands’ are the carbon fibre mini-masts
that are fixed right at the top of the mast, with wind vane and anenometer fixed
to them.
The World Sailing Speed Record Council

anerkennt und auflistet. Die Entscheidung, ob man als Zielpunkt The Lizard oder
Ushant ansteuert, hängt auch von der Anwesenheit eines Kontrolleurs der WSSCR
ab.
