Just thought I'd look at the drag for the different hull shapes.




Hull1 is a conventinal "blade" design, hull2 is a moth planing bottom design similar to what Wouter and John are proposing, hull3 is a Gcat type Deep V design. All hulls are 12ft long and are displacing 120kg. The slimmer Gcat hull has the lowest drag, but there is not a great deal in it.

With regards to hull 2 this program does not predict planing so if the F12 will plane at higher speeds then there could still be a benifit in going that route.
