In boating it is one of our great allies. We are talking about the vang, which allows you to adjust the vertical position of the boom, thus changing the profile of the mainsail. One of Italy’s leading manufacturers of boating accessories,
Bamar
, produces efficient and super-reliable ones.
What it is and how to use it
Cocking the vang brings the mainsail leech to tension, flattening the sail and giving a small bend to the mast. This adjustment is done upwind in a strong wind, while in lighter air you simply have to point it, so that the mainsail is shaped correctly and the boom does not dance. In carrying swells with sustained wind, the vang is essential to depower the sail. Leaving it, if there is a risk of straining, will raise the boom, warping the sail. Having a poorly designed vang circuit, or a system that is outdated and at risk of breaking down, will not only prevent the mainsail from working well by invalidating performance. But it will endanger boat and crew. So if there is any upgrading to be done on deck, it is on dear old vang that we recommend you take action.
The mechanical spring vang designed by Bamar
Bamar
who designed and made a vang equipped with an internal spring that pushes the boom upward. The series consists of 6 models for boats from 9 to 19 meters. The length can be customized on board at the time of installation. The
Vang
is made of silver or black anodized aluminum alloy with two telescopic tubes equipped at the ends with special attachment ends with built-in pulleys that form a compact top hoist with the possibility of return to the cockpit. The line can be locked onto the Vang itself using the additional hoist.
