The trajectory as far as Lizard Point isn't as clear as all that: after Newfoundland we're going to have to choose between a route which sees us heading up a bit or bearing away a little, which has repercussions on the sail configuration. We're going to take that decision after Cap Race... The crux of the matter still centres on the end of the course as the front looks to want to drag its heels as we approach the goal."
Sylvain MONDON (FRA), Groupama 3's onshore router, also explained the reasoning behind this start time, as Pascal BIDEGORRY and his crew opted to set out from the Ambrose Light two and a half hours later (Wednesday 29 July at 22h 47' 42'' UT): "Last night, a line of squalls passed over New York generating fairly strong Southernly winds (25-30 knots), which enabled us to set off a little earlier than planned. This decision is supported by the fact that within a few hours of the departure time, the course time was the same: taking the start a little earlier enables us to have a little room for manoeuvre in relation to the depression system which will accompany the trimaran after Newfoundland. A cold front has formed over Canada and will traverse the Atlantic as far as the British mainland: Groupama 3 will catch up with it as she approaches the Labrador current and keep slightly away from the front. As such it will be easier to control the trajectory by staying a little closer to the great circle route (direct route). It's a very good weather window as it prevents us from extending the course whilst remaining on the same tack."
Newfoundland, the nerve centre
As such Groupama 3's trajectory promises to be very rectilinear as far as Lizard Point and the passage permitting a more or less direct route towards the goal is less than 20 hours ahead of the giant trimaran. It is worth recalling that the warm current associated with the Gulf Stream is helping the multihull's progress, but as they approach the Grand Banks the temperatures will drop right off as they come face to face with the cold Labrador current, which runs along the East coast of Newfoundland. Fog, damp, shipping, fishermen... there are any number of obstacles dotted about this stretch of the course, but from noon on Friday, the path across the Atlantic will be clear with relatively calm seas because as the multihull catches up with the Canadian low, this system will push the Azores High southwards, leaving a soothed ocean in its wake.
Last night, CAMMAS and his nine crew initially had to deal with sandbanks scattered around the start of the course off Nantucket. Compelled to sail twenty or so miles to the South of the direct route, Groupama 3 was able to slip along this Thursday morning and improve her attacking angle in relation to the wind (25 knots of South Westerly, sailing 130° off the true wind). As such, she has repositioned herself this noon onto the shortest route by stealing a lead over a cold front associated with a low coming across from Canada. The aim is to stay ahead of the front so as to hook onto the same stable South Westerly wind all the way to the area surrounding the English coast. In order to achieve this, the average speed will have to be very consistent throughout the course and sailed on a single tack (contrary to the record set on 24 July 2007 by Groupama 3). Their improvement on the reference time of 4d 03h 57' 54'', should therefore be appreciable by Friday evening, as the green trimaran had to put in three gybes a long way South of the direct route two years ago...
The 'hunter' Pascal BIDEGORRY, who set out from New York a little over two and a half hours after Groupama, was maintaining the same pace as CAMMAS: it remains to be seen if the separation at the start will cause their trajectories to diverge off Newfoundland tonight!
