Vang-Master 3 - 1/2" Pin Dia (25 - 36 ft Boat)

Harken collaborates with Marine Products Engineering to offer Vang-Master rigid pneumatic boom vangs. Vang-Master boom vangs use air pressure to provide extension force to hold the boom up, without the need for metal springs. This reduces parts and weight while keeping operation squeak-free, providing an infinitely adjustable, turnkey solution for maintaining optimal mainsail shape. Construction is hardcoat-anodized 6061-T6 aluminum, making them light and strong. Tubing and end fittings are threaded together eliminating fasteners and dissimilar metals to reduce corrosion.

The vangs are designed to be easy to install. Options available are external purchase systems which feature Harken hardware exclusively. They come pre-measured, spliced and finished with line specifically-selected for the application. Harken distribution makes the vangs easy to obtain, while offering fast turnaround on spare parts and technical service. Harken Vang-Master products come in four-cylinder diameters with a menu of 120+ build lengths for everything from Moore 24s to Andrews 70s. Use the boat’s pin-to-pin measurements to achieve a precise fit. Stainless steel mast and boom fittings and custom lengths are also available upon request.
