Rick,
Glad to see that you are owning up to making mistakes. I never do and I
never make mistakes. It's always someone else that has caused the problem on my
boat. Your PO must have been a large person or had large people for crew.
Having the seats crack where they meet the hull is a new problem that we haven't
had to address on the list before. I do know of one heavy set owner that added
support to the seats, but only to prevent any problems from occurring.

Rummy,
Glad to see you back on the list to titilate our discussion.
My mast step was delaminated and had detached. The delamination is from
water penetration which, if you bribed me with enough rum, I may admit to
being my fault since I have torn out the mast foot plate and may not have
re-sealed the screws properly when I re-attached the plate. The yard
attacked the step because the gelcoat was cracking around the it.
When I bought the boat, it was 5 years old and the weight of the mast was
deforming the cabin roof. After sailing it a season in choppy Lake Erie,
the cabin roof was getting worse. I don't know if the PO started the
problem by over-tightening the stays or it was just because he sailed the
boat in Lake Erie since it was new. Anyway, that's when I put in the
compression post, locating it according to Stan's advice.
Another problem I've had from Lake Erie chop is gelcoat cracking where the
cockpit benches join to the cabin bulkhead. The same yard did a great job
solving that problem by reenforcing the benches with wood stringers. The
benches don't have that nice natural spring to them anymore, but my bins
still slide under and lock just the same. And I have the thick sealed-cell
foam cushions, so my butt isn't that much worse off.
Despite its weak points for Lake Erie, the yard guys love the R22. Their
standard advice is to reseat all deck hardware every 5 years. After 15
years of absolute neglect by me and the PO, my boat only had water
penetration in the mast step and the outside edge of the head hatch (and for
a little more rum--well, I did replace that hatch.) Anyway, their advice
for the R22 is every 10 years.
