The S-1 Jib is a heavy jib with a 100% overlap, built for the most extreme wind conditions, typically over 21+ knots. Made from 6.5oz cross-cut Dacron, it features a forward track sheet and a hank-on attachment and a removable luff wire, making it compatible with both furling and non-furling forestays. Designed for heavy air, the S-1 Jib is ideal for lighter teams, or extreme conditions.
