So the resistance should be optimized for a higher speed. But don't quote me on that. I don't know such things. /m The prismatic coefficient is quite high, if I remember correctly.

Maybe there is something in what Tom say's about the transom fooling the water into thinking that the boat has a longer waterline than it does. Stuart.
