Right: This trimmers view shows the top 77% of the sail. Sheet tension is adjusted so the top spreader patch makes gentle contact with the upper spreader. The spreader patch is perfectly located to make contact with the rig at mid-patch. Unlike the light moderate set-ups in the above photos, this set-up is best for acceleration and rough water.
