I have a 1973 Ericson 27. On the last outing of the year my main blew out . I cannot afford a new one right now so i am looking for good used main to replace the old one.
Try North Direct. I got a great price on a new main and jib for my SJ26 from them. It was very little more than several of the used sails. Good sails too. The logo on the main is North Sails. Google North Direct.
Only 1 match for an E27 main. A new, unused dacron CS27 main for $700. A really close match for size from the specs. I would get that North quote for comparison.
Wow, I new mainsail for $700! I need a smaller boat.
