This book is an Owner's Encyclopedia for the Catalina 375 yacht, created by Catalina 375 owners. It is created and maintained by members of the Catalina 36/375 International Association. It is not designed to duplicate all the information found in the Owner's Manual, but for all those "details", such as part numbers and sizes, and pictures. The kind of stuff you wish were included in the manuals! Members are encouraged to add facts (not opinions!) to it.
