This simple 4:1 self-cleating vang is used on small dinghies. The vang allows vertical adjustment of the boom, and is an extremely important tool to shape the main for speed. Tension the vang to tighten the leech, flatten the sail and bend the mast. Cruisers use the vang to keep the boom from rising when sailing downwind and abraiding the main.

Typical boat length: 
Small Boat: 8' - 28' (6.7 - 8.5 m)


Comes with Harken V-Jam Fiddle Block (245), Harken Double Block (226) and 25' of Samson WarpSpeed II - Dyneema Double braided 1/4" competition grade line.
