| Boom Vangs | |
|
A Boom Vang lets you control the leech tension of the mainsail independently of the mainsheet so you
can
better shape the mainsail for maximum efficiency. 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.
Rope (soft) Vangs are also used in Downwind situations as a Preventer - the Mast End is simply
moved to an attachment point on the rail to help prevent the dangerous unintended Jibe. 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 Bails are used for attachment points on the Boom and (on smaller boats) often on the Mast, though there a variety of section-specific Vang Brackets for individual Mast Sections. For these items you'll need to identify your Mast Section, See Spars. Note that some Mast Steps and Deck Collars already have integral Bails or other provisions for attachment of Rope (soft) Vangs. Soft (Rope) Vangs
- Block and Tackle with an integral cleat and Shackles on each end. |

| Soft Boom Vangs | |
|
Soft (Rope) Vangs are basically a block and tackle with an integral cleating mechanism as
part of one of the blocks and Shackles on each end. Some Soft Vangs have Snap Shackles
(on one or both ends) 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 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. |
