Sunfish Fleet 680

Hailed as "the most popular sailboat ever built," the Sunfish is still going strong after more than fifty years. Its popularity is partly due to its low price and easy portability, but it also sails well and is a lot of fun for both beginners and experienced sailors alike. This is a daysailer for active sailing, as it's mostly a single-handed boat. You're likely to get wet unless the water is flat and the wind is light, but for sheer fun and ease of sailing, the Sunfish is terrific. As long as you remember to move your body (the ballast) when you tack and gybe, you really can't go wrong with a Sunfish.
