    There's an old saying in the aviation industry "with enough horse power, even a brick will fly" and they've proved it with some of the aircraft designs that are around. The very same thing will happen to boat, with enough horsepower any boat will plane.

    Agreed, I work for Lockheed, and they certainly proved a brick flies (F-117).
    For a boat I was hoping for a little more elegance, I always believe 10 HP should send a Tornado at 20+mph, but I know very little about powered boats.

    BTW, Gary Dierkings sent some infor on the tornado which says he got 13.8MPH from a 10 hp Honda outboard.

    Of course, the Tornado probably doesn't totally plane by anyones definition, but it has been clocked on the race course at around 27 mph sailing (I don't know the specifics of how the timing was done and that was 10's of years ago)

    whats with the v bottoms, most of the aussie powercats in that size have flat bottom or nearly flat bottom hulls. bruce harris, sailfish, markham , noosacat and powercat are mostly flat bottom, if you google any of those names you might find some pics to study. but all of these brands need plenty of power to perform . kevlarcat and marlin broadbill are a couple more i can think of.

    i also agree with par, you can purchase plans for a proven design and concentrate on building rather than reinventing the wheel. richards skoota is a great looking design and you can find plenty of praise for his designs on the net. he would probably alter it within reason to suit your needs, you could be out fishing instead of trying to design your own. i don't mean to put you down or discourage you but the few boats i have seen designed by amateurs have been wrong in one way or another. powercats are sensitive to trim, so much that the poorer designs are bloody dangerous in quartering and following seas.

    Since I've been told by so many people that this is above me, I've decided to build a smaller one first. I'll aim for 12 ft.

    no one is trying to put you down, just stating facts. if you are set on designing your own boat you will do it, i just think it is wasted time trying to design a boat when there are so many good and proven plans available. there is a big difference between drawing a boat on your pc and building it. what about material sizes and types, frame spacings, what construction method. all these questions are already answered when you buy plans. if you build your first boat off a plan then you will be so much wiser when you do your own design.
