Garhauer Deck Hardware – Rope Vang – Two Speed Mainsheet System

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. 

This makes handling your mainsheet a bit easier. If you pull both lines, it is a 3 to 1 ratio (or as some people refer to it as gross tune). If you pull a single line, it is a 6 to 1 ratio for fine tuning.

Note : Rope not included.
