Many thanks for the very kind words.
This boat features a little bit of refinement on the sail, hull, stern planes, and especially the propulsor. The real boat features stators that have a twist to them that delivers the flow to the impeller at the most efficient angle. The aft set of stators straighten the flow back out after passing through the damped impeller. Yes, this impeller is skewed back. You will notice an increase in overall speed, and due to the design of the forward & aft stators a better turning radius. A retro fit would not be that difficult. I will supply the parts to you at no cost if you are wanting to do that.
