JVT: Wind and Waves for Groupama 3

The sailing conditions will become harder this Saturday evening with the arrival of a cold front via the West, which is set to catch up with Groupama 3 whilst causing the wind to shift round to the same sector. As a result the giant trimaran is being forced to climb upwards and is likely to gybe at least a couple of times to line herself up with the third cap...

Cape Horn - its very utterance conjures up images of the wind you expect to find there. Hoorn, the town which gave its name to this promontory, this peak, this black, dismal, grim, steep isle, surmounted by an improbable lighthouse which the majority of Cape Horners haven't had the chance to see. Indeed it seems that the winds and seas, the squalls and fog want to hide what is often referred to as the "Hard Cape"... Another four days then to get the hoped for glimpse of this symbolic milestone, which marks the end of the Southern Ocean...

"Under full mainsail and gennaker, we're slipping along at between thirty and thirty-five knots: it's going well! There's no violence in the conditions, other than the fact that it's cold... That comes as quite a change since we plunged to the SE after Tasmania. It's wet and things are steaming up a bit inside the boat. We're really beginning to get accustomed to these average speeds now. Cape Horn is our next course mark, at which point we hope to have a slight lead over the reference time before we begin our ascent of the Atlantic. If everything goes to plan, we have every chance of extending our lead a little... if the sea state doesn't deteriorate too much" explained Fred Le Peutrec at the 1130 UTC radio link-up with Groupama's Race HQ in Paris.

Moonlit accompaniment!

A lead of almost a day on this 27th day at sea: 570 miles ahead of Orange 2's virtual wake. Furthermore Groupama 3 is continuing to streak ahead at a rate of 130 miles a day! Indeed even though Bruno Peyron and his crew were able to lengthen their stride in the Pacific Ocean, Franck Cammas and his men certainly aren't being outdone with thirty knots still visible on their speedo.

"There will be a full moon tomorrow, Sunday: it's very pleasant and the extra light is enabling us to helm more accurately so we can catch onto the waves. The nights only last around six hours with a long twilight and a big dawn. We're at the most isolated point from civilisation, but we're closing on land quickly! We'll make Cape Horn fairly soon, however we're going to have a little more breeze than forecast. As such we'll have to fully bear away, close to the following wind, which will enable us to withstand some fairly strong winds. The sea is set to run in line with this stiff breeze, which shouldn't stop us from sailing fast."

The all-pervading cold

This is the most complicated section of a round the world. Indeed making landfall at Cape Horn is the most S'ly point of this Jules Verne Trophy at 55° 58' S and 67° 38' W. Logically, the Chilean islands will be within their sights from Wednesday evening (UTC), but the men on Groupama 3 will have to remain vigilant over the next few days as icebergs have been pinpointed in the area close to the Amundsen Sea. The biting cold of Antarctic is finally making its presence felt ...

"We hoped to be making fast headway along some straight trajectories without putting pressure on the boat and that's exactly what's happening. During The Race in 2001, I recall a more intense cold. Since the start of our entry into the Deep South, things have been going really well. Naturally conversation has touched on our capsize off New Zealand but today the most tangible dangers are the icebergs! The sea temperature is cold and we should pass by the icebergs without seeing them, though we do have a radar. We know they're there... Great lumps of ice without the cartography aren't a virtual danger. We're remaining lax but concentrated."
