Duotone Mast Slim - 2026

The Mast Slim 2.0 D/LAB from Duotone is a high-performance, one-piece mast engineered for maximum efficiency, rigidity, and speed. Designed with a slim, low-drag profile, it delivers precise turning behavior and controlled handling across advanced foiling disciplines. The monobloc construction enhances structural integrity, supporting high-load performance and consistent feedback.

Each mast length is individually optimized for its intended application, using High Modulus Carbon fiber with tuned fiber orientation to maximize bending and torsional stiffness. A redesigned drag-optimized base plate reduces resistance during take-off, touchdowns, and landings. The tapered chord length and thickness profile further refine strength-to-drag balance, while the mast’s ventilation-resistant profile—particularly in longer sizes—ensures stable performance at speed.

The Mast Slim 2.0 D/LAB utilizes the 3BS connection system, compatible with all 3BS fuselages and D/LAB wings. It is available in three lengths tailored to specific riding styles, from prone and downwind to freerace and larger surf conditions.
