    Macif /Francois Gabart have confirmed their choice of the radical west option, the faster in theory, but more complex with transition phases (of light wind) to perfectly manage. Gitana, still leading on the N-W direct route, and Actual Leader (behind at 400 NM) are now in another timing and routing logic. Rendez-vous at the end of the week at the entry of the Doldrums !

    The 3 Ultims are now oriented to North. Gitana is sure to enter soon the Doldrums with a solid lead, they did Cape Town - Ecuador at an average speed of 24,8 Knots. Now Macif has the wind from South-East which should able them to accelerate a lot : is this will be sufficient to recover the second place in font of Actual Leader ? Answer in the next 24h.

    Macif is now second again after 24h at an average of 28,4 Knots, they got the fruits of their west option. But still at more than 600 NM behind Gitana which did an express crossing of the Doldrums (at over 21 Knots) and already in the North trade winds with an optimal angle to go fast. Probability of a win is very high now for Franck Cammas and Charles Caudrelier.

    The 3 Ultims are now out of the Doldrums less active than 2 weeks ago, Gitana still with a confortable lead of 600 NN / Macif and 680 / Actual Leader. The race is not finished yet, the final includes strategy to round the Acores anticyclone and a downwind rush likely on sea state in winter weather.

    Gitana continue its lead at 22 Knots in irregular wind forces but probably sufficient to catch a Low that can give it a south wind and the opportunity to go directly and fastly to Brest (expected Wednesday morning). Macif and Actual Leader are clearly in another scheme, they are fast on water (> 30 Knots) but slow in VMG, having to round light winds zone by the West.

    As expected, Gitana can now take advantage of the south edge of a Low to go directly to Brest with a good speed, 29 Knots in average, of which 25 of VMG, during the last 4 hours. 1150 NM to go for them.
    On the other hand, Macif and Actual Leader, now far behind Gitana at 1100 NM, have to cross an anticyclonic corridor of light winds to be in a similar situation. Macif should probably have some technical problems because, theoritically faster than Actual Leader, they cannot show extra speed consistently.

    Gitana took full advantage of the south edge of the Low, doing 722 NM during the last 24h (30,1 Knots in average). Now 455 NM to go, arrival expected upwind in East wind, for this night or tomorrow morning in the daylight for the show ! Macif and Actual Leader, side to side (just 10NM between them) still blocked in a light wind zone moreover moving like them, patience, patience, ....

    Some figures about Gitana 17 victory :
    Average speed 24,57 Knots on water (17084 NM , for 13752 theoritical) , with a best 24h at average 30,9 Knots.
    From Charles : "We were in flying mode about 50% of the time, We could fly more " (in particular without this daggerboard damage issue from Cape Verde to Bahia)"
    It is the accomplishment of a 4 years project : 2 years for the conception/construction , another 2 years for the learning curve and the first failures correction (a great thought to S├ębastien Josse the first skipper who did a lot for the progress of this sailing machine).
    Men hours for such Ultim project :
    ~ 15000 h for the naval architecture, ~ 35000 h for the engineering studies, ~ 70000 h for the building
    And again : floating objects...!, the unfair misfortune you can face at any moment, the probability is high and the damage important due to the speed, forcing two pit stops (Gitana, Macif) and an abandon ( Sodebo).
