I was in the same boat so to speak not so long ago, I sent emails to McNamara and Batt sails but got absolutely no reply from either, so after asking around I remembered Hartley’s and now have a great set of sails (Hyde) that work as well as my original set (McNamara), and was given a few good sailing tips for free at the same time. The secret is “Don’t sweat the small stuff”. Use that plastic card wisely!
