To say a Hobie 16 is agricultural would be kind. It is the Harley Davidson of beach cats. They keep dressing it up but it's still a tractor. If you are not going to use it in surf run. Even huge fleets don't excuse its bad behaving. I run several cats including the old 16 foot Tornado copy the Hydra which is about the same vintage.
I took a nat champs H16 sailor out on it recently and he was super gun shy of plowing the nose in.. kept pinching and not giving the boat its head.. who needs that?
Get long noses, dagger boards, over power the boat and go up wind. :" )
Seroiusly though I think it is about mind set. If you will get into sail trim, tactics and the beauty of sail go the Nacra, if you just want to be a monkey and thrash about the Hobie will probablly give you the laughs.
Whatever the choice, sail fast! : )
