Her are two different online manuals
http://www.catalina22.org/manuals/mnl77/manl77.htmhttp://www.catalina22.org/manuals/mnl87/handbook.htmOne is for 1977, the other is for 1987. When I bought my 1975 C22 SK, it did not have a manual. I phoned Catalina Yachts, the builder, not to be confused with CatalinaDirect, the parts supplier. Catalina Yachts mailed me a 1977 manual for free, and the tech I spoke to said that they didn't have any older manuals remaining, but the '77 manual is pretty similar. My opinion is that so is the '87, just don't go by the standing rigging sizes for your older boat from the '87 manual.Here's a link to CatalinaDirect.If you are going to keep your boat and plan on making any repairs or upgrades, you'll need to save these links. Also, buy the catalog from CatalinaDirect. http://catalinadirect.com/Good Luck!
