Roller furling
Mike-- I installed a Schaefer Snap Furl on my OD25 last summer, and bought it from Defender at a great price. It requires no modification of the headstay at all. It turned out to be a tailor solution, literally "made" for the boat. I then made the rounds of the sailmakers, all of whom wanted big $$ for a new RF genny that in their estimation would win the America's Cup. Some never bothered to return my call. Those that did wanted almost as much to convert my own genny, which meant they were really trying to sell me a new one. So they were really not interested in a small "sale of a sail" to "small potatoes" like me. So I contacted Sails East on the web (who I'd seen at Annapolis the year before) and they made me a beautiful 150 genny for less than two thirds of the price the big boys wanted. The workmanship and service was superb. Chances are your old sail is tired anyway. In the alternative, you might have a cooperative small sailmaker in the New Haven to New London area who would be reasonable about your request to modify your sail. Good luck!
