    Lifting Foil on Trimaran Daggerboard-Martin vs Maserati

    From Martin here today: http://www.catsailingnews.com/2017/04/edmond-de-rothschild-gitana-17-maxi.html#more He says:

    " Good to see no central main foil (at least as shown for now) having a Trimaran using a central main foils seems ackward feature and can hurt non foiling mode as shown by Maserati. Macif is testing one thought for Gabart's next big Tri though.
    Trimaran offshore systems are yet to be consolidated, but I would go no mainfoil for the central hull."


    --------------------------------
    Maserati says:

    "First trimaran in the world to fly with effortless stability on the horizontal loading-bearing surface of her centerboard, Maserati Multi70 brilliantly puts into practice Guillaume Vernier and his Team’s idea of flying on three resting points using a load-bearing centerboard, L-foil and a rudder instead of the two rudders and single foil adopted on America’s Cup cats.
    Giovanni Soldini and his Team are engaged in a new challenge as they endeavour to turn Maserati Multi70 into the first ocean-going flying trimaran. An ambitious project that spans not just Guillaume Vernier’s excellent work (he worked on the modifications to her appendages) but also over 4000 nautical miles of sailing clocked up by the Team this summer.
    The straight central daggerboard plays a revolutionary role in this new flying trim as the horizontal load bearing surface at its end generates lift, raising the boat out of the water. “When Maserati Multi70 rises up on her lateral foil and rudder, the daggerboard wing acts as a third resting point – the central and largest one”.
    Tests in wind of 40 knots have demonstrated that Maserati Multi70 is now much more stabilized and able to fly in conditions unthinkable before. Safely tackling also big seas."

    daggerboard foil

    From what I hear and read the discussion about the use of a daggerboard foil on a trimaran is going on all over the world right now,especially, in ocean racing trimaran design circles. It will be really cool to see if any of the new boats being finished or started now wind up with such a foil or buy into Martins argument.

    Daggerboard foil

    =======================

    Heard today from Martin of catsailingnews.com that there is no daggerboard foil being tested on the converted 24' Diam.
    Thanks to Martin for the heads up.....
