We bought our 1990 34 over 11 years ago and are still happy with the boat. I agree with the recommendation to check all the items listed by gregry m below. Your prospective boat is over 25 years old, so you will hopefully find some items that he listed have already been addressed. Because these boats are initially on the high $$ end, owners typically keep up the maintenance. Your survey will identify most of the issues. It’s a real good value at that listed price, there’s a lot of room for upgrading if you buy it.
If not already addressed by former owner(s), the the following should also be considered:
1. Exhaust hose - replace
2. Mast collar - rebed
3. Masthead running and anchor lights - change to LED
4. Lifelines - replace
5. The galley sink bottom is at or below LWL. The sink drain assembly parts are often not marine quality. That is a weak link in the CR34’s mechanical systems. Be absolutely sure all connections there are corrosion-free, trustworthy, and the seacock is solid.
6. If mainsheet traveler is original, with finger-buster piston/button adjustment, consider a newer style line-control traveler.
7. Steering system’s aluminum mounting bracket assembly is hiding under floor of aft lazarette, often neglected due to difficult access. Check for corrosion and spray with corrosion preventative.
8. Original pumps, manual bilge, head overboard, and electric diaphragm bilge are certainly getting near the end of their useful life.
9. Original mainsail track and full battens makes raising/lowering sail nearly impossible at any angle except directly upwind. Consider adding a Strong Track.
10. Check water heater tank — often installed wrapped with insulation which absorbs salt water and corrodes tank bottom, where water gravitates.
