I have the chance to purchase a 1987 Catalina 30- tall rig, full 5'3" draft that has been on the hard for 10 years. Needs lots of cosmetic work. Main problem seems to be Keel to Hull fitting-1/4" gap at front, showing. Don't know about engine yet. Is fixing the Keel to Hull a big job? (reasonably handy with glass).Are there any things I should look for with a boat that thas been out of the water so long?
