Duotone Foil Assist AL Cruise 80cm Set

Freeride

Mast Length: 80 cm
Harness Sizes: S/M – L/XXL

The Foil Assist Cruise Alloy Mast Set is the ultimate entry point into assisted foiling. Purpose-built for beginners, progressing riders and schools, this setup delivers smooth, predictable performance with the power and safety features needed to build confidence fast.

With a slightly shorter 80 cm mast, the Cruise version offers improved stability and forgiveness while still performing impressively in swell, chop and small waves. Whether you're learning your first flights or teaching others, this mast makes foiling easier, safer and more accessible.

Key Features & Benefits

Low Drag, Clean Integration
A fully integrated motor pod, positioned 15 cm above the fuselage, combined with internally routed cables creates a streamlined, low-drag profile. This results in smoother glide, better balance and intuitive handling, while keeping assembly quick and simple.

Stiff Alloy Mast for Smooth, Predictable Control
The rigid, surf-inspired alloy mast delivers direct feedback and reliable response without feeling twitchy. Reduced flex means better efficiency, easier control and confidence-inspiring performance for newer riders.

Highly Modular & Brand Compatible
Designed to grow with your foiling journey, the Foil Assist Cruise Mast AL allows easy motor and cable swapping across the entire Assist mast range. Choose your fuselage adaptor when you order to fit your existing foil from Duotone, F-One, Gong, Axis, Lift, North, Code, Sabfoil, AFS or KT. The mast mounts to any mid-length foilboard using standard US tracks.

Beginner-Optimized Setup
For first-time riders and schools, Duotone recommends pairing the Cruise mast with the Midfish Air. This durable, forgiving board enhances safety and allows the battery box to be mounted on the tail, offering an alternative to wearing the harness.

Powerful Thrust for Effortless Takeoffs
Equipped with a high-torque motor delivering up to 33 kg of thrust, the Cruise Mast gets riders on foil sooner with less effort. Perfect for learning proper stance, balance and control without constant pumping.

Folding Propeller = Low Drag & Added Safety
The folding propeller only spins when powered, minimizing drag while gliding and increasing safety during falls or water starts. For riders needing extra punch, optional aluminum power propeller blades can be added for increased torque.

Reliable Signal & Consistent Power Delivery
With the receiver housed directly in the harness battery box, signal strength remains strong and consistent. Expect smooth, reliable propulsion with an average runtime of approximately 30 minutes, ideal for lessons and training sessions.

Propeller Guard for Extra Protection
An easy-to-install propeller guard (secured with three small screws) adds an extra layer of safety, making this setup especially well-suited for beginners and instructional use.
