Default soft, spongy cored decks - repair method and costs?

\It really depends on how much is good and how much is soft in any
amount. If there are any more than isolated soft spots be prepaired to
pay out some bucks or spend a year in hell. Otherwise, I would look for
another boat.

Soft decks means moisture in the core. Real soft decks means rot. You
will need to rip down to the lower skin back to solid core and then
another foot or so of top skin only. Let the edges dry out, recore and
reskin and then fair out to the original deck. You could core with
plywood but the added weight will raise the COG and make the boat a
little more tender.

Also if the rot is extensive you better make sure how the cabin top is
supported. On many production boats the side decks provide most of the
support for the cabin. When you remove that support the cabin top must
be held in place by temprary bracing and tied carefully into the recored
side decks.

I am considering a purchase of a long neglected sail boat. I am
confident of my ability to assess and estimate time & costs for mot of
the issues involved in bring this vessel up to good condition, except
one problem. The cored deck is soft, very soft in some places. The cabin
top is not cored and is in good condition, except around a couple
opening ports where the ports were torqued down so tight to stop leaks
that it began cracking the fiberglass.

But it's the decks that worry me as I have never done a repair of balsa
cored decks, nor had reason to consider such costs previously. This boat
is out of the country, btw, so I would be depending on yard work done in
either Grenada, Carriacou, or Trinidad. Before talking with yards about
this, I would like to have better info of what is likely to be involved
so that I can better assess their plans, proposals, costs. This is for a
36' boat. Recommendations on yards or personnel in those islands
welcomed.

I can feel the softness, and in many places see the indication of cracks
in the nonskid around the soft areas, pretty much defining the places I
feel. In one place I can make the deck squeek by standing with feet
apart and just shifting weight between them.

Can anyone relate their experiences and costs with such repairs? Or
point me towards good source materials about the subject.

I am also wondering whether I could sail the boat between the islands
mentioned above to get to a preferred yard for the work. The mast is
deck stepped, the cabin top under the mast seems stiff, and the shrouds
are not deck mounted but rather to the hull and internal bulkheads. I
could also motor as the engine seems fine for its age.
