I was a Santana 20 dealer, and raced against them for years before that. PHRF 222 most places. The boats enjoy large fleets and often race one-design. They have been the boat selected for the Price-of Wales national match racing competition. Will sail way past their number by a skilled skipper/crew. SAIL IT FLAT! A fierce competitor in light air. Fin keel much quicker. A great deal of "refinements" and rigging know-how have been developed for this boat. Very racer-friendly design in deck layout.
The only drawbacks would be limited cruising space for more than an overnighter, and cockpit has no real seat-backs for leisurely sailing.
1350 pounds with a 550 pound keel, 8 foot beam is considered beamy for a 20' boat. Again - SAIL IT FLAT!
