Hello all you knowledgable sailers out there enjoying this summer! I got a question regarding stainless steel bolts, First of all, I don't know who built it. It's a custom sloop made in France around 1988, and presently I am cleaning up the bildge. I see stainless steel bolts pertruding out of the lead pour around my centerboard trunk in various places that is encapsulated in an aluminum enclosure, which you probably know, is my keel. I am trying to understand how and in what way, these bolts help secure the keel to the hull. Now I have heard of "J" & "L" bolts but don't see a nut that would secure the bolt to a crossmember where it would make sense, unless it is under the lead pour. Anyone familiar with boat building technics related to lead keels?
