Catalina 320 Hull History and Design Changes


The C320 has evolved greatly since its introduction in 1993. This table attempts to capture as much

information about where and what changes were made along the way. It is quite incomplete at this point

but will improve over time if owners contribute data.


If you own a C320 and can provide details about your hull, model year, and any other info that will help

paint a more complete picture, please feel free to send your information to the webmaster. Specifically,

we don't know which hull numbers belong to which model year, unique features or problems you've had

fixed, etc.
