Waydoo FoilBoost Assist Kit for Foiling

Waydoo FoilBoost is a modular foil-assist system designed to give existing foilers a controlled boost when they need it most. It is built to help with take-offs, extend sessions in marginal conditions and make light wind, small bumps and tired legs less of a barrier to getting on foil.

This is not a full eFoil and it is not intended to replace good foiling technique. Instead, FoilBoost sits in that very useful space between pure foil power and a full electric foil board: enough assistance to help you get flying more often, while still keeping the feel, skill and freedom of normal foiling.

For riders who already foil, or who are very close to consistent take-offs, it is one of the most accessible ways into electric foil assist. It is especially interesting if you want a more affordable, retrofit-style system rather than committing to a full eFoil or a higher-priced assist platform.

Where FoilBoost sits in the foil-assist range

FoilBoost is best thought of as an accessible, modular assist system. Compared with a full eFoil, it is lighter, simpler and much more focused on short bursts of help rather than continuous powered riding. Compared with premium foil-assist systems such as Foil Drive or Duotone Foil Assist, it is aimed more at value, ease of fitting and progression than maximum power or the lowest possible drag.

Choose FoilBoost if you want help getting going, recovering from touchdowns, stretching lighter sessions and building confidence without spending full eFoil money. If you want continuous powered cruising, a full eFoil will make more sense. If you want the most refined surf-style feel or maximum power for advanced downwind use, it is worth comparing FoilBoost with other systems in our foil assist collection.

Who it is for

• Wingfoilers who want help in marginal wind, easier restarts and a better chance of getting back upwind when conditions fade.
• SUP and downwind foilers looking for earlier lift, more margin between bumps and more confidence when conditions are not quite perfect.
• Prone and surf foilers who want assistance getting into weaker waves or recovering from lost speed.
• Progressing foilers who are close to consistent take-offs and want more repetition without exhausting themselves.

Why choose the Waydoo FoilBoost?

• More usable sessions: FoilBoost helps turn marginal days into realistic foil sessions, especially when the wind, bumps or wave energy are not quite enough on their own.
• Controlled assist, not full eFoiling: You still foil, pump, turn and read the water. The system simply gives you extra help when you choose to use it.
• Accessible price point: FoilBoost brings electric assist into reach for riders who do not want to spend full eFoil or premium assist system money.
• Modular fitting: The system uses an adjustable mast clamp and pad arrangement to work with a wide range of mast chord lengths.
• Simple remote control: The wireless remote offers three gear settings, making it easy to choose how much help you want on the water.
• Dual-battery workflow: Waydoo list a 432Wh total battery capacity, with two lithium-ion battery modules and a charging station included.
• Safety-focused layout: The rear-drive configuration includes a propeller guard, and the system uses warning lights and fault indications to help keep use more controlled.

Specifications

Mast compatibility guide

Waydoo’s user guide gives mast chord compatibility ranges based on the pad and bolt combination used. These figures are useful as a guide, but they should not be treated as a guarantee that every foil, mast and board combination will be suitable. If you are unsure, send us your mast brand, model and a photo of your current set-up and we will help you sense-check it before you order.

Safety notes

• FoilBoost adds powered assistance to your foil set-up, so it should only be used by competent riders in suitable locations and conditions.
• Always start in the lowest gear setting until you understand how the system behaves with your board, mast and foil.
• Keep hands, leash lines, clothing and other objects well away from the propeller area whenever the system is powered.
• Do not use FoilBoost without the correct mast clamp assembly fitted.
• We strongly recommend a helmet, impact vest and a conservative approach while learning the system.
• Always rinse, dry and inspect the system after saltwater use, and follow Waydoo’s battery care and charging guidance.

Need help choosing?

Foil assist is one of those categories where getting the right advice matters. The right system depends on your weight, discipline, local conditions, current foil set-up and what you actually want the assist to do.

If you are considering FoilBoost, send us your current board, foil, mast and riding style and we will help you work out whether it is the right fit. We can also compare it with other options in our foil assist range so you can buy with confidence rather than guess.
