I had a very nice one made this year at Leading Edge Sails in San Mateo by Joe Rushka. He and his father own a Santana 22, so he knows what is needed. You also might call Spinnaker Sailing in Redwood City, who had new ones made for their Santanas this year. Theirs were made with a longer "overlap", which was done for the convenience of the students, who are not perhaps as inclined to fuss with very tight fits at the end of a day of sailing; the cover does "flap" a bit.
