I finally found something useable at 3w mycatalina30 net slash docs slash Catalina_30_Manual dot doc.
David, I'm sure there are a lot of peoplle who feel that way about Mr Butler and Catalina Yachts. Anybody who can sell more boats than his next 10 comptetors has to be doing something right!
Richard, Hopefully this will help you out with the 30. Apparently CY still has some owner's manuals available. I just lucked out and found this on the web. I'm a big fan of free! ;-)
