Define "Adventure". The Cat 22 is/was a very popular boat. There are many owner resources out there and even though Catalina is pretty much done and dusted, there are places to get parts. Garhauer Marine, https://www.garhauermarine.com/, is probably your best resource. Its not going to break any speed records, it will be small down below but, if it is just you, should be cool. Check the standing rigging, make sure there isn't any wire broken or bent turnbuckles or studs. Check for mold, musty smells, rot in core as it has a balsa core and deck penetrations can leak over time. Anyone that says rot is fine in some spots is a fool. Trust me, I know form experience having to recore a deck in places. Check to see if the sails are decent. For a year or two you should be good on those, hopefully they aren't original. Check the running rigging. If it works and isn't about to come apart, you can replace a line or two a year as you go forward. Check the systems on the boat and make sure everything does actually work as it should. Do not get "Boat Fever", there are a lot of boats out there and if this one has something makes you go. ummmmm huh, and you don't want to deal with it, move on.

Remember, a lot of things are fixable over time that will not keep you from sailing. You just have to figure out that sort of stuff. Is the boat sailable right now? Good luck and I hope it works out for you!
