    Nice, i'm wondering if the scow form will still be succesfull for a foiling mini. The weight adds up i think.

    It depends of the foils role and dimension, reflecting the designer expectation for this additonnal device : which fractions of lift (and so of RM) at wich speeds.

    My sorry Doug, I have not yet seen all your threads already showing us these developments.

    You saw that Imoca stay conservative on full flight capability, no lift wing on rudders, ocean singlehanded races versus full flight still a huge decision to take for organisers, even with self-righting boats. But may be an option for future AC if monohulls ?

    No worries at all-just wanted you to know about the other thread. I think the SeAir has rudder T-foils and I think the new full foling Vendee and Volvo boats will have rudder T-foils too-required to fully fly. Thanks for your input,Dolfiman!

    I think the scow shape is important to provide beam forward and improve lateral separation between the foils. It will also help for the inevitable nose–dives from ventilation. One big question is the through–hull fittings, they take huge loads when the boat is at speed, it will be interesting to see how well they can maintain their seal. I guess much has been learned from sealing off canting keels (though they aren't that well sealed), but now there are 3 such appendages, all taking very large loads.

    It will also be a challenge to keep the boats foiling, it takes a lot more concentration that any other mode. You can see in the videos that the boat is being very actively steered to maintain foiling, and that is in maybe 15kn of breeze and relatively flat water. It's being steered like a planning skiff, i.e. you go wherever the wind sends you to keep the boat under the mast. It will be quite a feat to come up with an auto–pilot that can sustain safe foiling.
