Re: Full or fin keel?

AVS refers to a boats righting ability.....there is another, sometimes called a "capsize screening ratio" which addresses how easily a boat capsizes, a good AVS doesn't mean a bad capsize ratio SloopIT - Boat performance calculator. The capsize ratio of my boat is 1.42....which is considered to be very good (2 or higher is not considered safe at sea).

William Atkin was famous for designing safe ocean cruising boats, the design of mine was commissioned with the intent of using it for ocean cruising. Of the 40-50,000nm (alot of which were ocean miles) the only comment regarding it's performance at sea was "It's a good sea boat" (from the owner that had here for 15 years and sailed everywhere from Mexico to Alaska on my boat and all over the world on others). I would take my boat to sea ahead of 95% of the boats in the harbor, I truly feel safe in my boat.
