    Got this in my private mail. Since I don't have the answer I'll post it here:

    {FROM: hamid_amini320
    i want to write a computer program for calculation speeds of sailing boat with use approximate equation (formula) , but i need a approximate equation for wave resistance .

    can you help me?}

    Can anyone help this man?

    I had a freind at uni who was rying to develop code for velocity prediction. His code never matched the tank tests and it was horribly complex.

    You can contact Dave Ogresta he may give you a few pointers

    Peter, i had sort of the same pm question from Hamid on "sailboat wave resistance". i advised a search for "wave resistance" on the forum or the net for lots of info and gave links to "freds calculator" and "mitchlett" thinking basically without all the variables resistance is resistance for sail and powerboats. later i realised i should have mentioned the yachtdesign software with more exact data, have to run, "vpp" in search above comes up with 3 pages but have to run now...
