What Is an eFoil? Definition, Technology & Getting Started

An eFoil is an electrically powered surfboard with hydrofoil lift – it rises out of the water at speed and glides across the surface in near-total silence. Driven by an integrated electric motor and a lithium-ion battery, it needs no wind, no waves, and no physical effort. Board, mast, wings, drive system, and remote control – these five core components make the experience possible. The Aerofoils eFoil takes things a decisive step further: a fully integrated jet drive – safer, more precise, with no exposed propeller.

eFoil Components: The Five Key Parts at a Glance

An eFoil consists of five main components – each with a clearly defined function, and only their interplay produces that sensation of gliding above the water.

Board

The board is the foundation of the efoil board. Premium models are made from full carbon fiber – the result: minimal weight combined with maximum rigidity. Larger boards with greater volume give beginners more lift and make learning to balance significantly easier. Advanced riders and pros move on to more compact, more agile shapes.

Mast & Wings

The mast connects the board to the underwater wings and the drive system below the surface. At the base of the mast sits the hydrofoil assembly: a larger front wing generates lift, while a smaller rear wing stabilizes the ride. The fuselage – the connecting piece between front and rear wing – determines how directly and precisely the eFoil responds to weight shifts.

The principle is comparable to that of an aircraft wing: the front wing creates lift through pressure differentials in the water. At speeds of roughly 10–20 km/h, that lift becomes strong enough to raise the board completely clear of the water – drag drops dramatically, and the ride becomes quieter and more efficient.

Drive System & Electronics – Jet Drive Instead of Propeller

Most eFoils on the market use an exposed propeller as their drive system. The Aerofoils eFoil takes a different approach.

Jet drive. Fully integrated. No exposed propeller. The Aerofoils eFoil drive is completely recessed within the fuselage – no rotating part protrudes freely into the water. All electronics are waterproofed and encapsulated within the board, transferring energy to the motor with seamless precision. This is the result of 20 years of aerospace engineering, developed by Bavarian engineers with roots in aviation. For riders, that means maximum safety and minimal risk.

This difference is not a detail – it is the defining safety USP that sets the Aerofoils eFoil apart from every other hydrofoil board on the market.

Battery & Remote Control

Power comes from a lithium-ion battery integrated into the board. The stored energy is delivered to the motor with precision via the onboard electronics – infinitely adjustable via a Bluetooth remote in your hand. Depending on riding style and model, the battery provides between one and two hours of ride time. Ease off the throttle and you settle gently back onto the surface; open it up and you lift off.

eFoil: Origins and Variants

The eFoil has its roots in the classic hydrofoil – a wing-based lifting structure that has been used in maritime and motorsport applications for decades. The first electrically powered versions for water sports appeared around 2017; since then, efoiling has evolved from a niche technology into a global water sports movement.

Today there are eFoil variants for every use case: high-volume beginner boards with large underwater wings for maximum stability, compact performance boards for pros, and inflatable models designed for schools and travelers. The core components are identical across all variants – board, mast, wings, drive system, and electronics – but size, materials, and drive technology vary considerably. Some models add a stabilizing fin to aid control at lower speeds.

A look at the market makes one thing clear: the differences between manufacturers lie primarily in the drive concept, material quality, and safety philosophy – and it is precisely here that Aerofoils positions itself as a category of its own with its jet drive.

The Riding Experience – What eFoiling Really Feels Like

Gliding above the water, no spray, barely a sound – eFoiling is an experience with no direct comparison. Many describe it as 'snowboarding on water': the same flow state, the same interplay of balance and speed, but surrounded by stillness instead of snow.

Unlike surfing or kitesurfing, you need neither waves nor wind – the eFoil generates its own propulsion, on lakes just as readily as at sea. Steering is done entirely through weight shifting: lean forward and you drop closer to the surface; shift your weight back and you climb higher.

The Aerofoils eFoil reaches speeds of up to 50 km/h – silent, emission-free, with no spray or wake. No combustion engine, no noise, no fuel. Just water, speed, and stillness.

Who Is an eFoil For?

eFoiling is more beginner-friendly than many other water sports – no wind, no waves, no physical strength required. Anyone with a sense of balance and the patience to take the first attempts steadily can learn to glide above the water.

An eFoil is well suited to:

• Water sports beginners who want to surf independently of wind and waves
• Experienced water sports enthusiasts – surfers, kiters, wakeboarders – looking to expand their repertoire
• Technology enthusiasts who want to experience premium engineering on the water

In practice, the ideal beginner setup combines a large front wing (approx. 1,500 cm²) with a high-volume board – more lift, more stability, faster progress. Beginners should look for calm, flat-water conditions for their first sessions. The best and safest introduction to efoiling is a guided eFoil lesson under supervision.

Riding an eFoil is more than a feeling – it is flying above the water, silent and precise, on a lake just as much as at sea. Those looking to get started will make the fastest progress with the right setup and a guided lesson.
