Older Pearsons are generally very solid boats. I've spent the last six years overhauling my 1984 422 and have found no significant structural issues.
However, like any older
boat they will probably have some issues to address. Assume the 70s models, like the later Pearsons were built with a cored
deck and maybe
hull. Unless the previous owner was really on top of this, probably
leaks around the
deck fittings like stanchions, winches, etc. Check all of these
carefully for
water in the balsa
core. If you find a really large or badly delaminated area then consider the time and cost of
repair.
A few other things to check, most are typical of any older
boat, some more common on Pearons.
1. Hull/deck joint. Is it solid, is it leaking?
2. Base of
mast. Some Pearsons (including mine) used a
steel baseplate in the
bilge to hold the
mast.
Steel +
aluminum +
salt water in
bilge = corroded bottom of the mast.
3. Chainplates and
rigging. Boat that old the chainplates need close
inspection.
Rigging unless replaced recently also.
4.
Engine. Always a question on older boats.
5. Bulkheads and floors. Any
rot, wetness,
delamination, still well tabbed to the
hull and deck?
