    Both foilers seem not to fly. The wind is now about 16kn, last days it was 18-19kn, downwind. A hull-flying foiler should easily exceed 20 knots under such conditions, especially while sliding down the waves. Actually, they sail 9-10-11 knots, not faster than non-foiling Minis.
    Something does not work in current foiling Minis...

    You are right, it is a bit confusing to see that the 2 foilers Cerfrance and Arkema 3 are not able to show some extra speed in these most favorable conditions, even though they did well in the first leg up to Finistere Cap in light winds, then reaching, then upwind conditions in waves. May be pure beam reaching is better for them than the present rear wind with gybes, or that it is troublesome to have the auto pilot under full flying ? The race is not finished, the leader is on a counter gybe and will loss some of his advance, Axel Trehin in the west is well positioned to contest the lead, and light winds are expected at the end.

    The finish is becoming rather uncertain between the 3 leaders due to patches of light winds at the arrival on Las Palmas : presently Team BFR/Francois Jambou is still leading with 13 NM to go, but with unconsistent speed between 0 to 2,5 Knots. Cerfrance / Tanguy Bouroullec is just 3,5 Nm behind and Project Rescue Ocean / Axel Trehin is 7,1 NM behind, both showing a bit more speed in average.
    Tracking is now updated every hour :

    And finally, the 3rd won ! ..with a bit of chance as usual when there are erratic corridors of light winds. So Axel Trehin first, Francois Jambou 2nd at 6 minutes, Tanguy Bouroullec with the foiler 3rd at 24 minutes. In his interview, Tanguy said he tore his medium spi offshore Portugal, he quasi not flies due to a very bad sea state, but he used them (for assist I presume) to come back on Jambou. Anyway, he is very happy of the polyvalence of his boat in the very various conditions of this first leg, and confident for the second leg with trade winds.

    May be interesting to remind you on the smart foils system of Cerfrance imagined by G. Verdier : the 2 half spans of each foil are not symmetrical, one is with a straight tip, acting both for lift when horizontal or nearly and as a daggerboard when vertical or nearly, the other one is with a curved tip, acting mostly for lift when horizontal or nearly, otherwise out of water. The struts also act for the lateral resistance when the foils are horizontal. Two visible degrees of freedom : retractable and canting foils. About the rake ? (No info, I think not). These freedoms allow a continuous graduation of the foils use with a low drag objective in mind , for lateral resistance, and /or foil assistance and /or for full flying.
