Hydroplane. One step.

 
















- There are only a 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'sstudy for a 24' simple, single-step hull. Numeca International, already mentioned in a previous post, provided the results.  sales@numeca.be

- Being a hydroplane she presents 2 angles of attack with 2 planing areas. The image below shows her riding on points amidships and aft to get a moment of equilibrium. Speed, as shown, is 34.5 knots.







Recent interest, May 2014 led to preliminaries for a 28' version. This longer boat might end up having 
another step built-in.
