Harken Hydraulics - Double Boom Vang
Harken Hydraulic vangs change the height of the boom to help control sail shape. They also function as a topping lift to hold the boom up when reefing and to keep it level when the sail is flaked. Harken® offers a full range of vang cylinders: single-acting air return for smaller boats and lighter weight booms, and powerful push/pull double-acting cylinders for larger boats with heavier in-boom furling systems or Park Avenue booms.
