Jacques, the smooth but pronounced twisting in the tunnel sides and ceiling is impressive. Not sure how you figured it out! As per your design specification, will be installing a 20 hp @ 3000 rpm Kubota based diesel, a 1:1 F-N-R box, and a 10 x 10 Michigan Wheel prop. Will be interesting to see how she performs.
As Peter-C notes, while it's a pretty wild looking hull, the wild parts are mostly underwater. As a workboat that will be stopping an starting all the time, she'll run skinnier than just about any other frequently stopping-starting boat. Wild functionality perhaps?
