I am looking at a 1981 Catalina 22 swing keel for about $3,5000.00. What features or optional and additional equipment should I be looking for to make this boat a good value? Are there certain things I should look at that should have been up-graded or replaced? Is there a better year model for the money? This will be my frist major sailboat to spend some time on and i am a bit of a novice when it comes to sailing. Any advice would be helpful. Thanks, Capt Mark
