It's not extreme weather and the waves don't reach the length of the foil itself. I'm curious as well as to what happens on rough seas.

Also totally different boat eh. Those waves are probably a little bigger than they look, but yes, definitely "better than average" I would say.

A quick search for “candela c8 rough” finds some?

Boy do I want one. For those calm days though. The quietness is another big draw. I have a 4stroke and it’s so peace destroying.
