I would avoid the boat. Never seen a non encapsulated keel where there is no access to the bolts (Cast Iron Keel) or nuts (lead keel) especially on a Jeanneau
The bolts may have been glassed over because of a problem. Maybe broken bolts or leaking bolts. This may have solved
the problem but may be hiding a serious problem. Like a keel missing bolts and ready to fall off.
If you do go ahead and haul the boat for a survey
, you will probably see the hull
to keel seam open up or possibly grounding damage. If so the glassing will need to be removed to get to the bolts and you will see what the glass is hiding. Interesting but not pretty.
If you are truly interested in the boat, don't worry about the steel
keel. Worry about the keel bolts. Find a good surveyor
and ask him if he can properly survey
a boat without inspecting the keel bolts. Expect a NO.
Unless the owner will expose the bots for a survey, I would run, not walk away.
