I have been looking at used Freedoms (80's) but have found that the builder did not seal any through-core/through-hull fittings. This becomes a problem as the boats age because it is usually the exterior caulking that gives up first and start leaking, and the interior does not leak until the core is good and wet.
How much damage is acceptable around a through hull before the whole thing has to be torn open and what is an industrywide rule of thumb for determining at what point the hull is permanenently weakened by a "peel-back" repair ???
