Lewmar Genoa & Traveller Track Size 3 – Beam Track (BM)

The Lewmar Genoa & Traveller Track Size 3 – Beam Rail (BM) is a heavy-duty reinforced aluminium track designed for extreme load applications on large sailing yachts.

This beam rail features a high-profile construction that delivers maximum stiffness and minimal deflection under load. It is specifically engineered for installations where the track spans unsupported sections, such as across cockpits or companionway hatches.

Thanks to its rigid structure, the track maintains precise alignment and ensures smooth movement of traveller cars, even under very high sheet loads. This makes it ideal for performance sailing and offshore conditions where reliability is critical.

Manufactured from high-strength anodised aluminium (6082-T6 extrusion), the track provides excellent resistance to corrosion, wear and mechanical stress.

With a profile of approximately 50 mm width and 55 mm height, this Size 3 beam rail is built for maximum load capacity and durability on larger yachts.

• 1500 mm (1.5 m)
• 2000 mm (2.0 m)
