This ultimate Optimist mainsheet is tapered and made of abrasion resistant PES material. Tapered from 9 to 6.5 mm. Thick and soft where it touches your hand. Thin and smooth elsewhere for free running control. Tapered on both ends. Long enough to create a 4:1 Optimist mainsheet with 2 boom blocks.
- 9mm to 6mm tapered FSE line (similar to Bzzz cord)
- Works with standard 4:1 optimist mainsheet systems with 2 boom blocks.
