Bob: Other than obvious appearance items, the main thing I look for
when evaluating an Express 27 is the soundness of the deck,
especially around the chainplates and other fittings bolted through
the deck. Deck rot on a poorly cared for boat can be extensive and
expensive to repair. You can evaluate the deck by looking for signs
of leaks and discoloration in the cabin on the underside of the deck,
by walking and jumping up and down on the deck, by tapping the deck
with the handle end of a big screw driver, or, best of all, with a
moisture meter. Some water in the balsa core is normal, especially
around the chain plates. But extensive water is a bad sign. It leads
to rot in the balsa core and ultimately to delamination of the skins
from the core.
I have also seen saltwater boats with extensive corrosion in just
about everything from the standing rigging, to the running lights to
all the deck fittings. (This need not be a major problem if the boat
has been religiously washed with fresh water after use.)
