    Well, the boat was launched-but NO FOILS!! I was looking forward to this -very disappointing......Gitana 17 is going from where it was launched to Lorient , presumably , for outfitting and rigging.

    No pictures yet but I found this little nugget recently added which confirms the daggerboard will use a lifting foil similar to Maserati:
    GuillaumeVerdier, naval architect
    “The initial idea was to design the first oceanic boat capable of flying with unfailing reliability. There are trim tabs on all the appendages. The central daggerboard has one too, a lifting surface in the form of a skate wing in order to increase stability still further when heeling and rolling. That is a huge amount for Sébastien (Josse) to trim. He's going to have to go at it in stages, learn how far is reasonable enough and also what hand to play when the seas are too heavy. There were 80 of us within Team New Zealand answering these questions. As such, we'll need to be patient and discuss ideas in depth to reveal the boat's true potential.”

    And for those that never read the "Planing Trimaran" thread-or who did and weren't convinced:
    Flat-bottomed hull and floats: As is the case on the America's Cup craft, the Maxi Edmond de Rothschild is equipped with three planing hulls with inverted bows and flat bottoms, so as to increase the ability to fly and provide excellent stability in heavy seas. The central hull and floats have a high freeboard for improved protection at sea.

    The text says it explicitly:
    "une dérive courte avec un plan porteur, "
    Seems that the moth way gains adepts.

    Thanks ,Corley-I wouldn't have thought to look there..... Big difference between this and Maserati since this boat was designed from scratch to use the daggerboard foil-going to be an incredible boat!

    Thanks Corley! He mentions the discovery of a "self-stabilizing foil" in 2010 or 2011 when he was at TNZ and says that this boat will use that type of ama foil-like an AC 72! Mentions that it is a large foil-larger than any other boat. I'm still looking for pictures but none of the ama foil so far.....
    UPDATE: A really fantastic interview-just watched for the second time and there is a lot of detail.

    Oh, brother....I can't find any pictures of the ama foils.They must be late-and/or the Team wants to sail without them first?
