Groupama 3: Slow rotation

Translation by Kate Jennings

Posted: 9  Feb. 2010

The position of the Saint Helena high isn’t favouring progress towards the Cape of Good Hope; Groupama 3 has been forced to pick out a course to the south-south-west before slowly straightening out her trajectory to the south this Monday afternoon and as a result, her lead over the reference time is diminishing.

Franck Cammas and his nine crew are still holding back a little in view of the grib files, which aren’t making the entry into the Indian Ocean very clear!

The high pressure in the Southern Atlantic is forming a barrier off Argentina and forcing the giant trimaran to trace a course way out to the west, along the Brazilian coast. Just 150 miles from shore, Groupama 3 made good headway over the weekend though, before the tradewinds switched round onto a more northerly track during the course of last night.

“On deck it’s really pleasant with glorious sunshine and a light breeze under large gennaker. Down below though, it’s an oven! We found it difficult to sleep last night as it was stifling.

“We’re finally diving southward now as the wind is gradually shifting round to the north-east. The breeze is fluctuating, but last night we were still able to sail faster than planned: we were regularly making headway at over 30y knots. As such, we’re a little bit ahead in relation to the weekend’s routing.

“We lost a bit of ground this morning as things have calmed down: we’re making headway at between 20-25 knots. The wind began to rotate last night between the clouds. We’re soon going to have to gybe when the breeze backs rounds to the north,” explained Lionel Lemonchois during the radio link-up with Groupama’s Race HQ in Paris at 1130 UTC.

Offshore of Vitoria this Monday afternoon, the crew will have to wait another day or two before they can straighten the helm!

It’s not yet clear whether they’ll be able to hook onto a cold front forming over Porto Alegre as it shifts across towards Africa. However, if they make contact at the right time, the descent towards the Cape of Good Hope will be extremely fast.

As a result, there is a considerable amount of work in prospect, as much on deck as at the chart table, in order to extract themselves from this tricky section as quickly as possible.

“We’re not going to be able to hang a left straightaway! We’ll probably have to link together a series of gybes almost as far down as the Roaring Forties before we can set a course for the east, said Lemonchois.”

“We’re on track to make a sizeable detour to hook onto a front in the south, but if we miss it, we’ll be two days behind on passing Cape Leeuwin. We’re going to have to pull out all the stops.

“The situation is changing from one grib file to the next so it’s still hard to know when we’re going to round the first cape, Good Hope. There’s going to be very little in it.”

In any case Groupama 3 should pass the symbolic 20,000 miles to go mark on this Jules Verne Trophy from noon on Tuesday.

Somewhat paradoxically, the giant trimaran is really lengthening her stride, but is losing ground on the reference time. By being forced to distance herself from the direct route, the 600 mile average across the water translates into a distance of just 305 miles VMG…
