Some things to look at...
The one thing I wish I had looked at but didn't is the electrical panel. Almost all these boats have owner mods to the (inadequate IMO) electrical system; I've had to redo several substandard additions. I would have gotten a clue about this if I'd removed the 4 screws holding the panel in place, and looked behind.Check the mast for kinks in the luff groove (possible indication of a mishap while stepping/unstepping). Make sure you raise and lower the mast with the seller's help a few times. This way you'll be familiar with the gin pole and side shrouds, and how they work. Go all the way, including unpinning the mast from the base and rolling it forward to the pulpit cradle. Check the T-bolts at the bottom end of each shroud; bent T-bolts are a common, easily remedied problem, but could be serious if ignored. The companionway is another common problem area. Most sticky hatch problems are easy to fix, mainly by dismantling, varnishing & waxing the slides, replacing worn bumpers and possibly trimming the width of the lexan panel itself. But one possible cause is of more concern. If the lexan hatch is sticky due to excess deflection of the cabintop on the starboard side, you could be looking at some tricky reworking to fix it. Hope this helps.
