visually. Bad glue joints at this stage might possibly indicate rot. I
would concentrate on the centerboard trunk and really give it a good
going over. Do the fore and aft decks cover sealed compartments? I
think the previous storage conditions may indicate whether you could
have a problem or not. If well stored you are probably worrying
needlessly.

Boat is OT (Fireball), but I don't think the question is.
The Fireball has plywood bulkheads, strengthened by frames. The fore and
aft decks conceal some of the forward and aft frames.
I'll never forget the dull "thud" of dry rot when I tap on rotten wood (had
another plywood boat once!), BUT, is there some way of detecting dry rot in
the frames which might be hidden by otherwise sound deck and top-side
plywood? I don't have an X-ray machine, unfortunately, and my x-ray
vision only works on what my nine-year-old gets up to when it's TOO quiet in
the house (grin).
Any suggestions as to how to inspect those hidden areas?
Thanks, everyone.
