Our Caribe with a 18HP Nissan does well.

my wife and I have a catamaran, which are sensitive to heavy loads,
especially aft. Frankly, we have a great RIB, AB 10' RIB, with a 5 HP
nissan engine. But the AB is heavy, and there is no way such a small
engine could get it up on a plane. I was wondering if anyone had any
input for what they liked for a planing dingy which could reasonably
plane 4 people (assume two couples, maybe around 700 lbs), but still be
light weight and plane well.
