    =========================
    If I were you I'd ask Hugh Wellborn as PS suggested. Alternatively you could PM Vlad Murnikov who is using a very similar foil on his Speed Dream Prototype and is working with Wellbourn. Wellbourn has done the full size and tank testing necessary to answer your question-nobody here would have any better knowledge on this particular innovation. Good Luck!

    PS- do you have any more info on the 38 footer-a link perhaps?

    Sorry, but the problem comes from Hugh and he has not solved it. We need to have someone who knows how waves behave near the hull from hull out to app 2m.

    Is it a displacement hull?
    UPDATE: I've found out that there is a problem with this boat but just so there is no confusion it is not a Welborn design-it is a retrofit. I'd be interested in more detail Bertil.

    It is an displacement hull. I have got some ideas of how to solve the problem and will count on it and will be back here on the forum when I,m ready.
