The hull IS coming apart; that's why I suggested either having it re-surveyed by someone who KNOWS WTF they are looking at or go back to the surveyor and ask for a second look or possibly put a claim in (but clearly not an option since it was an insurance survey). We know how the hull/keel is constructed; the question was about the LARGE CRACK running along the turn of the bilge at the keel stub (in a high load area).
I did not know that the survey was an after-thought to get insurance. It's possible that the surveyor was trying to do the owner a favor by not saying the problem is more significant in his report to allow the boat owner to obtain insurance; but I don't know what he was thinking or exactly what the problem looks like either.
To me, this longtudinal crack looks rather large; and scary. Is it just the picture or is the crack over 1/4" wide and ~6-8" long at the top? At the least I would think the area should be ground back to good glass and then layers of glass and epoxy filled in to the void; with a few layers of cloth over the top to aid in load distribution. But again, this is pure speculation; I'm not able to look directly at the problem.
