Great boat
I owned a '76 Catalina 27 several seasons ago and she was a great little boat. Atomic 4 inboard gas engine started right up every time and ran like a top. She was a very competent sailor and we had excellent luck with her before moving up to a Catalina 30. Just watch for the standard things on boats of this age - corroded keel bolts, rigging integrity, bad through hull valves, leaking chain plates, leaking ports, deck moisture and leaks around stantions, etc. Check out the Catalina 27 Association website for an article on what problems to look for in older 27s. A good 27 of this age has the added advantage of very little depreciation. We sold her for just $500 less than we paid for her.
