An interesting side topic, Pogo have debuted a 32ft power boat using their sailboat hull construction techniques.
Hull is a 25mm vacuum infused foam core layup, same construction technique as their sailboats. Complete with chine!
32 ft long, weighs in at 1750kgs with motor and cruises at 12 knots using 1/2 litre per mile with a Penta 75HP.
That's a sturdy construction for a stinkboat for a minimal weight penalty. And that was due to Christian, the guy who owns Pogo being a very talented composites engineer.

They need to work on the ugly factor a bit!
