I can see why you want to do it. The damn thing is made of lead and so it slows the boat down not to mention it gets in the way when you are in shallow water. That tongue in cheek aside, did they offer your boat in a shallow draft version? If so then the engineering has already been done. My boat was produced in a centerboard 4 foot draft version and a 5 foot version. I own the centerboard version but if I were going to convert I would just get the specs from one of my sisterships.
