I would also like to check in. My 25 is a standard rig, swing keel, made in 1979. Her names is Adventure and she sails Lake St Clair in Michigan. Having said that "OOMFH" (whoever he may be) is correct. You need to look into the association he mentioned. Just click on his link, and ask some one there to explain how to search the archives. There are few things to be aware of with the swing keel, check them out and enjoy the wind _/) GlenI have a 1982 25' Catalina, swing-keel, pop-up, standard mast, roller-fuller, 9.9 Suszuki. Has anyone inspected their keel bolt? Is it necessary? When? would I get a specific indication that I'm having a problem or will the keel just drop off. I don't trailer it a lot, maybe once a year. This is my first post. Thanks much!!
