WEST MARINE
Traditional Boom Vangs

Boom vangs control mainsail leech tension independently of the mainsheet so you can control sail twist. They’re particularly effective off the wind, when the pull of the sheet is primarily horizontal, because they prevent the boom from lifting and spilling the wind. We offer four vangs to fit most dinghies and racer-cruisers.

They feature snap shackles on each block (not on mini) so they’re suitable for both permanent and temporary mounting. High-quality components include New England Ropes double braid and free-running Ronstan fiddle blocks. You’ll need to add snap shackle attachment points on the boom and mast base.
