I just purchased a 1981 Catalina 22. According to the PO It's been in storage for the past 12 years. My question is what do I need to check prior to my first launch ? Second to my untrained eye the keel seems to be in fairly good shape. Is there any preventative maintenance that would help it last longer ? I'm moving up from a MacG regor 17 so I have just enough knowledge to be dangerous. Any help would be appreciated.
