James, measurements or not I'm actually quite impressed with what you've done to the hull of the boats to reduce drag. I think you're on the right track there, enough so that you may discover that you have more power than you need.

I too have been wondering about the feasibility of recycling old power cruisers and what what it would take to improve efficiency at displacement speeds. There are thousands of them out there across the US and many can be had for next to nothing.
