Bob, I read somewhere that it may also be under a cleat or winch. I would contact Catalina to find out or perhaps someone else here knows. I bought a 1976 C-22 with no title and by a process of elimination(and a bit of luck) I finally figured out the HIN, I then went to the DNR and contacted the original owner. I eventually got them to sign the boat over to me and the rest, as they say, is history! The guy that I bought it from told me I could NOT get a title(that was his first mistake)! Good luck to you!
