I like my Honda 3.8. Its lightweight when your dragging it round.
Its got big tubes, and the V in the keel at the bow is quite pronounced.
I've had it out in 2m swells and not felt worried.
what size engine are you putting on? I have a Yam 20d and to be honest its proibably the most I would want to fit. I think you could put a beefier unit on a non air floor.
the only other drawback to the Honda is its almost impossible to fit launching wheels as there are inflatable sort of trim tabs that extend out behind the transom. They do help it get on the plane quickly though.
