Duotone Mast AL 3BS QM (Mono) - 2026

The Mast AL 3BS QM (Mono) is an aluminium mast engineered to simplify foil setup through a tool-free mounting system. Designed with a one-screw Quickmount solution, it allows riders to attach and detach the foil without tools while leaving the base plate fixed in their preferred board position for consistent setup between sessions.

Featuring the updated AL 3BS+ connection, the mast maximizes compatibility across the Duotone foil range. The Mono Claw design incorporates standard foil mounting dimensions and delivers the same force transmission as a standard aluminum plate, maintaining reliable performance and structural integrity under load.

Available in 40 cm, 60 cm, 75 cm, and 82 cm lengths, the Mast AL 3BS QM (Mono) is compatible with Duotone Aero AL 3BS fuselages and D/LAB foils with fuselage tail. Helicoil threads are integrated to ensure long-lasting, high-strength connections and overall durability across foiling disciplines.
