[quote=bradinjax]I had a fathead main off a Prindle 18-2 so I had my favorite sailmaker "The Irish Sail Lady" in St Augustine, FL take the top panel off and redo the 45 degree batten. Ended up with a great squaretop main for my G-Cat 5.7. Best sail I ever tried on that boat. It was a Hobie 18 killer. Brad in JAX Stiletto 27 (x2)[/quote]
