I've always thought the overhang was odd, but this is how Albin set things up and there is no drivesaver. Prop is 24 X 24, 3 cup, 4 blade Hy Torq Nibral, the same prop configuration that they used with the 6CTA.
I don't have a picture handy, but the "tip to hull" clearance is about 4 inches .. I've been curious about adding a larger diameter prop, but haven't explored it with all of the other maintenance & refits that I've taken on over the last 4 seasons and now into my 5th of ownership.
