Hall Spars & Riggin - Home Hall Online Store

The Hall V-Boom is a highly refined and stylish addition to any cruising yacht or superyacht, providing a simple alternative to complicated and heavy mainsail furling systems.

This V-Boom, developed by Hall Spars & Rigging, widens the horizon in mainsail design. It accommodates a fully battened mainsail of any cloth, cut, or make. Choose a traditional mainsail track or opt for the Harken Switch Track system. Reefing is achieved with an internal sheave system with dedicated reefing lines led forward.

Advanced Composite Construction
Like every Hall spar, the V-Boom, constructed of pure advanced composites, is autoclave-cured under precise pressure and temperature control. Construction is pre-preg carbon and Nomex® honeycomb. Our careful tooling results in a precise fit and finish for a tough, weight-optimized, beautiful piece.

All-Around Safety
Safety is our top priority. During the design concept phase, we applied forces stronger than the unpredictable forces of nature to bend and stress our materials. Finite Element Analysis revealed the loads on the boom under stress, and we confirmed the findings with destructive testing. Our engineers then created a highly refined laminate to meet and exceed the expected challenges of offshore cruising. The result is a no-compromise design, ready to go to sea.

Key Features

Uncomplicated Design: Our careful tooling ensures a precise fit, and an impeccable finish provides a perfect match to the mast. Many custom features are available, from a choice of under-boom lighting to custom tapering at the outboard end to match your boat’s transom.

Highly Refined Systems: The canoe-like structure of the Hall V-Boom enables you to work safely in the boom even under sail in adverse conditions. All systems are easily accessible inside the V, allowing ease of service and removal. While you are sailing, the lazy jack system pulls forward, hidden out of sight inside the boom. At rest, the fully battened mainsail falls effortlessly into the boom, and the sail tucks away under its sail cover neatly stowed inside the V. The V structure can also accommodate a dinghy lifting pole, always ready but also out of sight.

Style and Sophistication: We offer a sunshade attachment and under-boom lighting strategically placed over guest areas in the cockpit. And the boom's finish can be either our impressive clear-coat carbon or the same highly polished Awlgrip finish used on the spar.
