The Catalina 350 International Association was developed in 2002 for furthering the enjoyment of ownership of a Catalina 350 and to promote camaraderie between owners. The Association is supported by Catalina Yachts and publishes articles of interest to members in the “Mainsheet” magazine. The specific goals are to:

  • provide the Catalina owners magazine “Mainsheet” to its members;
  • co-ordinate and promote cruising and social activities;
  • provide sources of information for maintenance and care of the Catalina 350;
  • promote the education of safe boating; and
  • co-operate with other yachting organizations.

This website provides links to a variety of topics of interest and value to all C350 owners. Some sections require registration as a member before allowing access, other sections are open to the public.

This received from one of our members:

An FYI for anyone who has their vessel documented. Today I received a letter from Maratime Documentation Service (MDS) in Montana reminding me that my boat documentation is due for renewal. It gives a phone number and email address for renewal. I called the USCG documentation center in West Virginia and was told this company, while legit, charges 3 times the normal renewal fee to process your renewal for you. The process takes me 2 minutes to do on my own when I get the official USCG renewal letter from the WV center. MDS also claim (for 3 times the standard yearly cost times 3) to handle your renewal for 3 years automatically even though the USCG documentation center only does annual renewals. The gentleman I talked to at the documentation center says he has had multiple people call to complain that their multi year renewal was not processed. That’s not the documentation center’s fault. While MDS is a legit business according to the USCG, to me it smells like a scam to be charged 3X the official rate for a “service” that takes a boat owner 2 minutes plus the cost of a stamp. You are also giving up your personal information and credit or debit card information. I got this scam like letter 4 months before my documentation was due for renewal. Save yourself some money and wait for the renewal letter from the real documentation renewal center.
