Ok do you mean wing keel or Fin keel? I don't believe that the fin was offered in 1986 but I could be mistaken. The wing was "officially" offered in 1987 and I know of only 1 wing from 1986 (mine) so I would be interested in your hull or sail number. As for the material the wing is led not steel. It is somewhat malleable and can be reformed if it gets banged up on the trailer too bad. Bolts on the wing should have been stainless and they are U shaped embedded in the keel so not easily replaceable.New owner of 1986 fixed keel. What's the material of the keel, lead or cast iron?
Many thanks --
