I don't know how much handyman or fabricator you have but here are my experiences. I once helped poor a keel on the beach on the Chesapeake by building a sand form and melting lead. I do not recommend that process now. The last
boat I purchased without a keel was a 30' Clipper
Marine. We, a couple of friends of mine and I, took a chain saw to a 35'
Morgan keel and inside an airplane hanger cut it to the proper weight and then formed a
wood nose for it. I glasses the whole thing, hung it in a yard and the boat is still in use some 25 years later. The Clipper
Marine were unique
boats having flat
steel keels for a
core and the airfoil shape made of
fiberglass around that. You could fabricate one without having to poor pot metal out of sheet
steel and then glass over it. Could easily be done in your back yard kind of thing. The one thing I will warn you of is the weight. Don't let it get away from you as it can easily do a great deal of damage to you and other things. By the way the last keel for that Clipper Marine took me 1 1/2 days to install. You have from all the responses the shape and you should be able to get the general location, etc from the
internet. Give it a try instead of parting it out.
