The SJ-1 Jib is predominantly designed to facilitate easier handling, particularly in the upper wind strengths. It would enable a lighter weight team to compete where previously they may not. It offers good pointing and is competitive upwind on flatter water.

The jib utilises the existing sheet but requires additional blocks to bring the sheeting angle forward to the aft side of the foredeck combing. The sheeting angle is much smaller and tacks very quickly without striking the mast.
