Since the lead keel
vessel is not an option, I would stick with the CI, and not swap keels, the old adage, if it isn't broke ... as you said before, dry bilge
no evidence of leakage, I wouldn't fool with it. As far as the lead goes, you might shop it around as a lead keel
first and if the money
isn't there then crank up the forge and start pouring, as the preious posted stated there is some serious money
in smaller bits preshaped, in my area a cast 16 oz banks sinker is worth $5.00 or more. It doesn't take a lot of heat to melt lead and you can buy the sinker molds off of ebay for not too much, it would be worth the investment.
