Foil Drive Assist MAX

The Foil Drive Assist MAX is the all-rounder electric foil assist system, engineered for the perfect balance between thrust, runtime and versatility across every foiling discipline. Part of the Foil Drive range, it bolts onto your existing hydrofoil mast to add power on demand — for longer surf sessions, reliable flatwater takeoffs, and easier upwind and downwind riding.

Providing an optimised blend of power, endurance and weight, the Assist MAX unlocks unlimited progression regardless of conditions. You choose your own battery size and motor to match how and where you ride.

Who It's For

• Discipline: Surf, wing, downwind, wake and flatwater foiling
• Level: Complete beginners wanting easier takeoffs through to advanced riders extending range and session length
• Best for: Riders who want one adaptable electric assist system rather than a fixed-spec eFoil

Key Features

• Choice of motor and battery – select High Power v2 or Standard v2 motor, paired with MAX High Power, MAX Sport High Power 396, MAX Sport or MAX Travel battery
• Up to 29kg max thrust – a thrust-to-weight ratio of up to 5.7 N/kg for genuine assist power, not a token boost
• IP68 water rating – built for repeated saltwater immersion and reliable long-term use
• V3 Wireless Throttle Controller – with charging pad, included as standard
• Minimum install weight of 4.8kg – with the MAX Sport battery, keeping the system light on your foil setup
• Complete kit – Foil Drive Gen2 carry case, multiple nose cones and motor pods, full hardware kit, tools and spares

Real-World Feel

The Assist MAX genuinely changes what's rideable — flatwater takeoffs that would otherwise need a boat pull or a lucky gust become reliable, upwind and downwind legs stop being a grind, and surf sessions run longer because you're not burning energy paddling into position. Peak power of 1854W (2.5hp) and sustained power of 1455W (1.9hp) give it real muscle across disciplines, while the modular battery and motor choice means you can tune the system towards runtime or towards raw thrust depending on your priorities.

Setup / Fit

Choose your battery (MAX High Power, MAX Sport High Power 396, MAX Sport or MAX Travel) and motor (High Power v2 or Standard v2) to match your priorities — bigger batteries add runtime and weight, the High Power motor adds thrust. The unit fits to your existing mast using the included hardware kit, mast cable guides and foam inserts.
