Don't know anything about teh 31 but I have a 28 cuddy and she rides great !Everyone I have spoken to states the same. "the toughest hull around ".

I run her with twin Yamaha 200's.

I just saw a Stamas 32 with galley,large head, and slept 4, that was sweet at a boat show in Puerto Rico. It also ran Yamaha (250's)
