Bill,

Are you suggesting that there is a such thing as a turtle-proof catamaran (in the context of this 'beach cat' discussion)? I disagree - I can't imagine any cat capsized with the trampoline bottom perpendicular to a stiff breeze that won't turtle. That is, unless it's equipped with some sort of a mast tip float. However, I'll concede that some are prone to turtling faster than others.
