Interesting interview with Mr. Fisher. Thanks for the link. Here's the part about the bow strakes:

What´s the story behind this extreme bow-rails concept?
MF: The idea is to force the bow wave to detach from the hull at a certain point. Thus the bow rail reduces the dynamical wetted surface.
The bow rail concept came as a result of the numerical simulations k-epsilon did on the project. The results showed, that the bow rails reduce the overall drag, it they are properly placed and if they have the right size. Without numerical simulations I never would have dared pursuing this path.
The raked bow is simply to reduce wetted surface and to reduce the windage of the windward hull.
(CS- Check post of January 2009 on Wildcat rails, actually Martin told me he read that post at the time and was that glad I didn´t say it was for generating "lift" or solely for strenght as expressed in many other forums..)
CS-More volume is the way to go in the class looking at latest designs, one main characteristic of the Cap, that was addresed with their new C2, was margin to push hard downwind (this even said by AHPC) the Wildcat seems to have more volume than the Capricorn, but still hasn´t the same margin as say , the Infusion or Shockwave. -This is a compromise you decided to stand (reduced bow volume compared to Infusion)? as opposed to excel upwind?
MF:During the development of the boat we also tested wider shapes.
The results of the RANSE simulations, however, showed, that there was a drag penalty especially upwind if we were going for wider hulls.
After discussion with Hobie and with some of the top sailors we decided to go for a moderately wide shape. The idea behind it is that many regattas are decided on the first windward leg, so being quick upwind pays in general.
