>>If you took all the presently available US built boardless beach cats in the 16ft, 17ft and 18ft length range and measured

Well the list that results from this condition is not really big is it ?

Hobie gateway
G-cat 5.0
Arc-17
Hobie 16
Nacra 5.0


All others like Mystere 5.0 are of course canadian. Other hobie products like the Pacific are European build. Isotopes and such are of course american build aren't boardless. I don't understand what boarded or boardless is imporant with respect to pitchpoling Than the Nacra 5.7 is longer than either 16ft. 17ft. or 18 ft. And so on and so on.

So what bill is saying out of the list of 5 boats, as given above, the "higher bow - higher pitchpole resistance" is valid.

Of course in general this is not always the case although it is often unlikely that taller bow boat is worse than a shorter bowed boat.

The counter example is of coure the difference between 90's generations A-cats and the new Flyer A-cat shapes. Here the smaller bowed hull has more dive resistance because of other aspects that were changed. However these don't fall under the definition as given because these boats have boards or are often produced outside the US. The A2 is of course US build but not available yet.
