I own a 2000 Catalina 320 purchased new in late 1999. It's a great boat. I've been completely satisfied with it and have to date had no maintenance problems whatsoever. I think it's a beautiful boat (the best looking boat in the marina). I highly recommend this boat. It has an excellent layout, dependable engine, good equipment, and is a pleasure to sail, both singlehanded or with crew.
The class organization (www.catalina320.org
) is very active and supports the boat well, so if you ever have problems, there's a knowledge base readily available. While they encourge people to join the organization, you can visit the website and participate in their forum list (just sign up for the list on the website) without being member of the organization.
I do not know of any C320's for sale, but suggest you join the forum/list at the Catalina320.org and ask on that website. You may be able to deal with a owner directly.
The Catalina dealer that I bought my boat from is Carolina Wind, Washington, NC. In buying my boat from them, they did everything that was agreed, and since I didn't have any problems, I don't know how that would have gone if there had been any problems. Carolina Wind might have a lead on some resale C320s, or a new one.
In Oriental, NC, there is St. Barts...a Beneteau dealer, but sometimes they have C320's listed.
I keep my boat in Washington, and at the present time, I think there are three on this creek, each at a different marina.
Good luck on your search. I don't think you will be disappointed.
