Boom Vangs

Boom Vangs
Boom Vangs are mounted between the Mast and the Boom and are used to keep the Boom from rising (without using the main sheet), and, in the case of Hard Vangs, to support the Boom (without using a topping lift). Vangs are normally mounted as close to the deck as possible (on the Mast), and from 30 to 40% of the Boom length aft (on the Boom). Boom Vangs come in two varieties, Soft and Hard (solid). Soft (Rope) Vangs are basically a block and tackle using line, while Hard (Solid) Vangs consist of an adjustable strut (usually metal) which is controlled with a line or by Hydraulics.

Soft Boom Vangs
Soft (Rope) Vangs are basically a block and tackle using line, and have a cleat as part of one of the blocks. Some Soft Vangs have snap shackles so they can be moved to other locations quickly, for instance as a preventer. In most smaller boat applications Soft Vangs are attached to the Mast or Boom with Standard Pivoting Boom Bails which attach with a single Bolt. Some specialized Mast and Boom Sections have special brackets and attachments. Select from those listed on-site under your specific Mast or Boom Section - See: Spars, or See: Boom Bails and Vang Attachments.

Hard (Solid) Boom Vangs
Hard (Solid or Rigid) Vangs consist of an adjustable strut (usually metal) which is controlled with a line or by Hydraulics. Non-Hydraulic units use line to compress them, and normally have a spring to cushion Boom loads and, in most cases, can support the Boom without using a topping lift. Hard Vangs are attached to the Mast and Boom with specialized fittings that are usually specific to particular Mast and Boom Sections. Select from those listed on-site under your specific Mast or Boom Section - See: Spars, or See: Boom Bails and Vang Attachments. Rig-Rite stocks a variety of Hard Boom Vangs, including those listed below.
