    That's a pity, they were doing quite well till now The Pacific was going to be interesting ...

    OTOH, when day went for the north Atlantic record, Groupama3 started before and and ended later, and BPV did over 900 nm in 24 hours while surpassing them. Both boats are lighter than back then and with shorter masts, but different conditions will still favour one or the other.

    First 2 gybes and vmg has plummeted ! And it looks like tomorrow they will end going north of IDEC's route .

    Or high, above sea level. Instead of giving a height in meters, meteorologists like to reference the point where there's a given pressure. Kind of balancing air mass above and below that point. I'll read it more carefully later, seems interesting. Lifetime averages still shorter than Joyon's ride, they were lucky !

    They are hanging in there, keeping a 350 nm ( or if you prefer, 8º of longitude , or about 10 hours at their "current" speeds of 35 knts) lead.

    As long as the front doesn't fall off of the environment ...

    At the beginning of the paper they define the mesocyclones as having less than 1000 km in diameter. That's smaller than than both, the one in front of SD2 and the one they are riding. And I've not checked, but I'm sure also smaller than the one that got IDEC across the Indian Ocean.

    So far it seems possible. That would be a good leap.

    That's what I wanted to say SD2 front is souther than IDEC's, which is good because makes for a shorter route, but could be bad if they have to abandon it to go north to avoid the ice. The there's the question of how far will it last.

    In the two attempts in the old Sodebo that turned in about a 2 months time, just a bit slower than the 57 days record that Joyon had back then, Coville sailed faster but through a much longer route. Weather luck, including how far south is possible to go without icebergs is key, not only because of distance gain but also to be able to profit the wind when the lows dive south.

    Last 3 days have been pretty impressive, and they think they can keep it up for another 2 up to the Kerguelen, and probably enter the Pacific with similar times if not ahead of IDEC. Looking at the 3D view is very obvious the shorter route they are taking by being further south.

    They expect them for Wednesday. Guichard: Mais on va aussi avoir des icebergs devant nous à partir de mercredi : il va falloir veiller au radar et aux lunettes à infra-rouges. Cela s’annonce un peu tendu… (Because they may have to go south of 53º) "But we'll have icebergs in front from Wednesday on: it will be necessary to keep watch on radar and with the infra-red googles. Prospects are a bit tense ..."

    They have pick up the pace and direction is very good regarding vmg.

    They can "easily" be 1 day faster in the Horn-Equator stint, but from the Equator to Ouessant IDEC was very fast. The Pacific will be important IMHO.
