2026 minus 1995 equals about 31 years. More or less, depending on month finished out. From experience I know that factory sealants (that seal ALL thru-deck fastener penetrations, have a reliable life of about 25 to 30 years at
best. Then you can expect water to start invading the core. Best way to counteract this oft-neglected problem is to re-bed ALL the fasteners. i.e. core rot is NOT inevitable.
The "gold standard" is to overbore, epoxy fill, and rebore every hole before reattaching all the tracks, cleats, blocks, rails, and a lot of etc. Use new best quality sealant.
I did this on our boat, and it's tedious but not too technical for a determined amateur. And, I was truly an amateur! In our situation we were also motivated by the need repaint the hull and deck, and restore the old nonskid to safe function again, so that was additional motivation. That, and having nothing better to do with our boat during the worst year of the Pandemic.
Hardest part of the project is probably going to be access to the nuts and washers on the inside. Ask, and I can link your to some photos in my blog.
A further upside is that now we have a "new" sailboat for a fraction of the price of an equivalent new vessel.
Further trivia: I and a buddy just visited the Seattle Boat Show and viewed a new Bene___ 34, and it was less well finished out than your boat and was priced at almost $400K. Cheap-o iron keel, too. Yikes.
Best of luck with your boat! I know several happy owners of that "hull design series" of Catalina (309, 310, 320).
Just opinion, but I believe your model will out-sail a Cat 30, handily.
