Re: what do you keel bolts look like?
It is the part that you cannot see that is the worry. These pics are from another thread (posted by eherlihy). The bilge pic shows just light surface corrosion but once the keel is dropped the real damage is visible.
As posted Beneteau type keels (cast iron) are easy to replace but a J bolt in a lead keel is not an easy nor inexpensive job.
