Thanks Pat, I had used the line drawing to estimate the shape of the keel but was looking for confirmation, I will fabricate a new one from 3 layers of 1/4 inch steel plate and it should be close to 200 Lbs give or take. Probably I will send it off to the galvanizer with the trailer I'm building. The mast I have is from something else but is pretty close. Are the spreaders fixed or do they have play? Thanks again, Todd
