Garhauer Deck Hardware – Boom Vang Fiddle Block Systems 

A boom vang is a line or rope system on a sailboat used to exert downward force on the boom and thus control the shape of the sail. 

Typically used as Mainsheet or Rope Vang, the 2 block system is available in five different size options. This fiddle block set up provides a self cleating, 4-1 purchase, with a clean free set up that wont cross lines.
