C320 Keel
Are you inquiring about the fin or shoal keel? As I recall, there were different variants of the shoal keel, the latest introduced around 2000.I would suggest calling Catalina and giving them your hull#, etc. and seeing what info they could provide. I doubt that the C320 Intl Assn or this Forum could give you much helpful info on this particular problem.Good luck.--RonD
