I'd say the air powered is faster. Consider that you're using an airplane engine right? When used in boat type of application... with driveshaft & water propeller, its not going to have the rev's to keep up. But used for what it was intended (to pull air through blades) it will be better suited.

We've seen guys at our lake convert an airplane engines for the use inside of a hull and it goes, but far from impressive.

The hull design is going to need to be suited towards one design I'd think.

It sounds very exciting and I'm interested in the outcome. Keep us informed.
