DETAILED DESCRIPTION
Design and Stiffness
The AL 3BS aluminum mast provides a tangible stiffness on the water. The connection between the fuselage and mast is extremely tight, giving you precise control over your foil. You'll feel an immediate power transfer when loading the foil in a turn or accelerating hard, allowing you to make instant course corrections.
Drag and Performance
The mast's refined profile minimizes drag, resulting in a smoother, more efficient glide. On the water, this helps you carry more speed through your transitions and gives a more stable, predictable feel at lower speeds. If you're looking for a ride that isn't thrown off by chop, this mast's low-drag design is a key advantage.
Mounting and Durability
The high-walled base plate, combined with a bonded and screwed one-piece connection, creates a highly robust structure. Helicoil inserts prevent the threads from stripping and keep screws tight, a crucial feature for heavy, regular use. This construction eliminates weak spots and ensures a long-lasting, reliable connection between your mast and fuselage.
Compatibility and Assembly
This mast is designed to integrate with Duotone Aero AL 3BS+ and D/LAB fuselages. The one-piece bonded and screwed connection makes for a simple, solid assembly with zero play. This compatibility means you can swap out fuselages to fine-tune your setup without changing your mast-to-board connection.
Choosing Your Length
Four lengths are available: 60, 75, 82, and 90 cm. As a rule of thumb, a shorter mast is great for shallow water and gives a more direct feel. A longer mast offers more clearance and stability in choppy or open-water conditions. Choose the length that best suits your body size, local spot, and riding style.
Rider Profile and Disciplines
The DUOTONE MAST AL 3BS 2025 is for riders who want a responsive connection and a solid platform for performance foiling. It's ideal for intermediate to advanced wingfoilers and foilers who need a mast that can handle frequent sessions while delivering excellent glide.
