For those that can explain....

Just how much banging/bashing and squashing... can a boat take before you can no longer "trust" the hull - even if obvious damage does not show?

I'm told - this "is" an issue of raising the wonderful wrecks that have been always sitting out of view, just under the surface in many places off Tortola
The saltwater damages the invisible plywood/wood interior structure - and you can no longer trust the integrity
