Bracket vs hull extension vs stretch????

[todosier]

Hull lengthening changes the hull rocker, which affect the angle of attack when coming on plane, planing and when falling off plane. With the VDH hull I would think you would positively have to have a pad or flat planing surface extended on the keel to enhance longitudinal stability, and lessen wetted surface drag. The alternative would be calculating hull rocker and building that into your extension.

Yes thanks, I haven't measured rocker along the keel or any of the panels for that matter. My thinking without those measurements would be none as you said for the small amount of extension I'm talking. I would like to add an absolute minimum of length to get the flotation to support the motor. I'd add one foot if I could, but I have a full transom on the boat and I'd rather not cut it up to put a motor well in, since I like the rear of the i/o as is.
