This plywood outrigger power boat is being built in Martha’s Vineyard.

We started with the 20 foot power proa as a template,  and modified it for a slightly bigger motor and simpler structure using less carbon reinforcement.

This boat has a fuller bow and the outrigger depth and trim were tweaked based on experience with he 20-footer.
