There are only few small aluminum boats featuring single step hulls. The concept is making in-roads with fiberglass construction being more amenable to be molded in quantity. Nevertheless I wanted to see a CFD'study for a 24' simple, single step hull. Numeca International, already mentioned in a previous post, provided the results. email@example.com
Recent interest, May 2014 led to preliminaries for a 28' version. This longer boat might end up having
another step built-in.
