DUOTONE ELECTRIC - The Foil Assist

Introducing the Duotone Foil Assist, an innovative solution that addresses the challenges of existing foil assist systems and eFoil boards. Unlike many products on the market that suffer from added weight and drag from batteries and motors, this cutting-edge system is lightweight and seamlessly integrated, consisting of three fully integrated mast options, a harness with a battery box, and a watch ring remote. This design allows you to enjoy the pure feel of foiling without excess weight in undesirable places by keeping the battery weight close to your body while maintaining a full range of movement. Additionally, the Duotone Foil Assist offers increased torque and thrust, enabling you to get on foil even sooner and use smaller foil sizes.

The unique remote design keeps your hands free, making it ideal for paddling, duck-diving, holding a wing, or managing a paddle.

The Duotone Foil Assist is compatible with all foils, including the Duotone Free, Glide, Whizz, and Carve models, as well as all wing and prone boards featuring standard US foil tracks. To maximize battery runtime with your Foil Assist, we recommend using a front wing with a surface area of 900 cm2 or larger, along with a board that has a minimum volume of 35 L. We have developed a dedicated midlength foilboard that offers extra benefits when paired with the assist mast. This versatility enables a broad range of applications, whether you're prone foiling in waves, wing foiling in light winds, learning to pump, cruising on flat water, or going for long downwinders.

For newcomers, the Foil Assist simplifies the learning process, making it easier to get on foil and execute takeoffs in waves. Experienced riders will appreciate its ability to provide smoother, longer rides with less effort, allowing them to avoid strenuous pumping when getting back out to catch the next wave. They will also be able to ride smaller foils, catch more waves, and tackle downwinders with ease while reaching swells farther from shore.

With the Duotone Foil Assist, you can significantly increase your time on the water, transforming mediocre conditions into exciting sessions. Explore new areas with ease, ride wave after wave, and enjoy longer sessions without physical fatigue.

Experience the pure joy of foiling like never before with the Duotone Foil Assist! 

KEY FEATURES:

DRAG-FREE DESIGN AND EASY SETUP

The motor pod is seamlessly integrated into the mast profile, with internally routed cables, ensuring optimal glide and maximum maneuverability. The modular motor pod allows for simple gear assembly and is easily removable, attaching to all three offered assist mast options. The mast itself attaches to the board as usual, making the setup process a piece of cake. 

HIGH-PERFORMANCE MOTOR WITH FOLDING PROPELLER AND SAFETY STOP

The powerful motor delivers unparalleled torque and thrust (33 kg), making it the most advanced option on the market. The propeller opens instantly when the motor is engaged and stops and closes immediately when the remote is released or when the rider falls off the board.

MINIMIZING DRAG & WEIGHT

To keep the board-foil setup light and perfectly balanced, we have integrated the batteries into a lightweight waist harness. The ergonomic design of the harness allows for a full range of movement, making it ideal for extended or high-performance sessions, while the plug-in battery system makes installation and swapping effortless. Additionally, the placement of the battery on the body offers another significant advantage: optimal signal transmission to and from the remote, resulting in consistent power output.

COMPATIBILITY

Our assist masts are compatible with foilboards from all brands that use standard US foil tracks. The AL masts can be used with products from other brands through the fuselage adapters. We recommend using at least a 35 L midlength board and a 900 cm2 front wing. Lighter and skilled riders will be able to ride down to their favorite foil size. However, please note that using smaller foils will consume more battery power.

WATCH RING REMOTE

The Ring Remote Controller frees your hands for paddling, duck-diving, or handling a wing.
Its intuitive, safe, and ultra-responsive design ensures a natural and seamless riding experience,
providing total freedom of movement. 

COMPLETE, LIGHTWEIGHT, STYLISH SET AT AN ATTRACTIVE PRICE POINT

Duotone offers a comprehensive, extremely light all-in-one package, including the foil assist set, board, fuselage, and wing set, all at a competitive price. The fully integrated mast and stylish design contribute to a clean and premium aesthetic.

HIGH-PERFORMANCE, TRAVEL-READY BATTERIES

Our 7Ah batteries are designed for maximum range and efficiency, featuring a capacity of 159.6 Wh - just under the 160 Wh limit and compliant with airline regulations. With optimized power output and smart energy management, they ensure consistent energy from start to finish while preserving battery lifespan. They can last up to 300 to 500 cycles depending on maintenance, with an approximate runtime of 35 – 60 minutes based on various factors.

SMART CHARGER – FAST CHARGING & BATTERY PROTECTION

To maximize your sessions, our Smart Charger optimizes battery performance with fast charging capabilities (approx. 45 minutes), allowing you to get back on the water quickly. It features automatic power regulation, ensuring consistent performance and longevity for your batteries.

MIDFISH FOILBOARD

The Midfish Foilboard was specifically designed for the Foil Assist. Its extended fishtail design reduces drag, makes takeoffs easier, and enhances safety for the propeller and cable. The forward foil box position improves takeoff control and creates the feeling of riding a smaller
board when foiling and carving.
