if the Owner is going to make repairs himself if he's a capable person to do such a job, I would ask that he document the repair with photos, material list anticipated procedure and receipts.
the keel boats are whats tying the weight of the keel of the hull
. My guess the encapsulation is doing more to protect the soft lead from being damaged.
when this happens in steel
keels and is ignored, you end up with rust and likely a lot more problems as the rust, like a cancer spreads around and tends to want to expand and cause more de lamination.
Was the delam caused by a "freeze/thaw" Ie water
got in, didn't get out, and then froze and popped?
if it was my repair. I'd remove the grp that is around the parts
that had separated above and below the crack until I got back to areas of good adhesion of GRP and lead. dry it out. Then start rebuilding. The keel bolts
are what holding the keel on. all you are looking at to my unpracticed eyes is a mostly cosmetic repair with proper glass work
, fairing, gelcoat/barrier coat, prime, AF paint
. maybe 10-15 hours worth of work
depending on how large of an area.
the trailing edge crack is a bit odd but could be just someone tried to fair the keel at one point and the fairing didn't grab hold or they used the wrong materials and it cracked. surprised that there are not any crack showing near the keel/hull joint, as thats were most cracks will form on a bolt on keel as the keel and fiberglass "move around"
I am not a NA, nor did I sleep at a holiday last night.
