You hear the term variable deadrise kicked around a lot, some even refer to the difference between entry and transom deadrise as variable - well no Sh*t ! The thing about the Seacraft hull is really those distinct steps, the vertical edges of the steps provide great tracking, the steep center deadrise gives you a soft ride while the outboard flatter deadrise adds stability.I believe the design was patented in the beginning, but has since run out and I've wondered why you don't see more manufacturers using it these days ?
