Duotone Mast AL 3BS

The Duotone Mast AL 3BS is the workhorse aluminium mast in Duotone’s current foil system, built for riders who want a stiff, direct feel, broad compatibility and everyday durability without stepping straight into premium carbon pricing. If you want one mast that can cover a wide spread of foiling disciplines and still feel precise under load, this is the sensible place to start.

For a lot of riders, this is the mast that makes the most sense. It gives you that connected, planted feel between board and foil, but with the kind of toughness and value that suits regular use, travel and progression. Whether you are winging, prone foiling, SUP foiling, pumping or putting together a dependable mixed-use setup, the AL 3BS is designed to keep things simple.

Where it sits in the range

Within the Duotone mast line-up, the Mast AL 3BS is the practical performance option. It sits below the carbon masts in price, but it is not an “entry-only” product. It is for riders who want real stiffness and a dependable connection, and who would rather spend their budget wisely across the full setup than chase marginal gains too early.

If you want the easiest possible rigging routine, the Duotone Mast AL 3BS QM (Mono) is the better fit thanks to its tool-free quick-mount system. If your priority is the lightest weight and highest-end feel, look at the Duotone Foil Mast Aero SLS Carbon or the Duotone Foil Mast Aero Slim D/LAB. But for most riders wanting performance, longevity and value, the AL 3BS is the mast that gets the nod.

Why choose the Duotone Mast AL 3BS?

• Stiff and direct on the water – gives you a connected, confidence-inspiring feel through turns, touchdowns and recoveries.
• Strong value in the Duotone system – a serious performance mast without the price jump of carbon.
• 3BS+ compatibility – works within Duotone’s newer foil ecosystem, making future upgrades much easier.
• Durable aluminium construction – ideal for riders who want dependable day-in, day-out use.
• Covers multiple disciplines – suitable across wing, prone, SUP, pump and more depending on chosen length.
• Smart length options – four sizes let you tune the setup for shallow water, all-round use or rougher conditions.

Which size should you choose?

If you are unsure, the 82cm is the safest all-round choice for most wingfoilers. The 75cm is a good shout if you want something a little easier and more manageable, while the 90cm is better for riders who know they want extra height and clearance.
