An explanation of the difference between a user account and Membership:

There is a difference between creating a user account on this website and joining the Association as a Member. You may already have a user account on the website (it is required in order to post to the Forums), but that does not mean you are necessarily a Member of the Association. There is no charge to register for a user account on the website; Memberships are available at various pricing levels.

Member Benefits

Becoming a member of the Catalina 36 International Association gives you access to a wealth of information on Catalina C36 and C375 boats that is not available to the public.  As a Member, you'll not only be able to communicate with a network of sister boat owners through the Forums, you'll also have access to our vast Technical Library of how-tos, articles, tutorials, manufacturers' manuals, and more, to help solve your boating problems and answer your questions. We also provide several discounts from vendors that are available only to Members.

Additional Web Content

In addition to the Community pages, as a Member of the Association you'll have access to a wealth of technical documentation, and the Catalina Yachts Mainsheet publication, and of course you will be able to post in the very active C36/C375IA Forums.  Here's a summary of all of the Members-only content you will be able to access as a Mainsheet Member of the Association.

  • Reference Manuals
  • More than 150 Member-contributed “How To” Maintenance and Upgrade Articles
  • Boat Encyclopedias
  • Important Notices
  • Catalina Yachts Mainsheet Magazine
  • Archives of the Association's JibSheet E-Magazine
