eFoil Speed: How Fast Does an eFoil Really Go?

Quick Answer

An eFoil cruises at a relaxed 20 to 30 km/h, and sporty riders travel at 35 to 45 km/h. Our hardboards, meaning boards with a solid shell instead of air chambers, reach up to 50 km/h (Adventure) or 55 km/h (Performance and Competition). Depending on wing and weight, you take off at around 20 km/h. Below that, you ride slower on the surface, but it's still relaxed.

• Cruising: 20–30 km/h, sporty: 35–45 km/h, top speed: up to 55 km/h
• Bigger front wings, the main wings under the board, lift off earlier, smaller ones make you faster
• Flying saves energy, full throttle and rough conditions drain the battery faster
• Motor power says little about speed, wing and weight say a lot
• Which rules and speed limits apply depends on the water you ride on

You've seen the videos: someone on an eFoil, a surfboard with an electric motor and an underwater wing, gliding silently across a lake. Now you're wondering: how fast is that, actually? And does it feel scary or relaxed? These are exactly the questions we hear from people all the time.

In this article you get real numbers on eFoil speed instead of marketing promises. We explain at what speed an eFoil takes off, how fast our boards are, and why the wing matters more than the motor. We also cover how your riding style affects battery life and what to look out for with the rules on your water.

eFoil Speed at a Glance: How Fast Does an eFoil Go?

An eFoil cruises at a relaxed 20 to 30 km/h, and sporty riders travel at 35 to 45 km/h. According to the spec sheet, our hardboards reach up to 50 or 55 km/h. Depending on your setup, you take off at around 20 km/h; below that, the board rides on the surface like a boat.

The values in the table are guide values from our experience. Your actual speed depends on your wing, your weight, the riding mode and the water. For comparison: 25 km/h is roughly the speed at which an e-bike cuts its motor assistance in Europe.

Because wind forecasts and nautical charts use knots, we list them too. One knot equals 1.852 km/h.

From our experience: Most riders spend most of their session cruising between 20 and 30 km/h. That's where the board sits calmly, the battery lasts a long time, and you have time to react to swimmers or boats.

At What Speed Does an eFoil Take Off?

Depending on wing and weight, an eFoil takes off at around 20 km/h, a little earlier with big front wings and light riders. Below that speed, the board rides on the surface like a boat; above it, you're carried by the wing alone, on the mast, the vertical strut between board and wing.

Takeoff speed is the speed at which the front wing produces enough lift to raise the board and rider completely out of the water. From that moment, the drag of the board in the water disappears. The ride gets quieter, smoother and more efficient.

You don't have to fly to have fun, though. Below 20 km/h the board lies on the water and you cruise along comfortably, almost like a small boat. On calm water that's relaxing, ideal for getting to know the board and for an easy lap along the shore.

You know the principle of flying from a car window. Hold your flat hand out and tilt it slightly upward. At 30 km/h you barely feel anything, at 100 km/h it pushes your hand up hard.

The front wing does exactly that, just in water. Water is around 800 times denser than air. That's why even a small wing works at low speed. How a hydrofoil, an underwater wing, works in detail is explained in our basics article How Does a Hydrofoil Work?

Why Weight and Wing Area Set Your Takeoff Speed

Lift grows with the square of speed and linearly with wing area. That's what the formula for dynamic lift describes. It leads to a simple rule: takeoff speed rises with the square root of the ratio of weight to wing area.

Three worked examples with our front wings, each with a comparable profile, meaning a similar cross-section shape. Let's say you take off on the Freeride 1350 at around 20 km/h, and you, the board and your gear weigh 100 kilograms in total:

1. Easyride 2000 instead of Freeride 1350: The area grows from 1350 to 2000 cm². Takeoff speed drops by around 18 percent, to about 16 km/h.
2. Freerace 900 instead of Freeride 1350: The area shrinks to 900 cm². You need around 22 percent more speed, just under 25 km/h.
3. Total weight rises from 100 to 125 kilograms: That's 25 percent more load. Takeoff speed rises by around 12 percent, to a little over 22 km/h.

Doubling the wing area doesn't halve your takeoff speed, it lowers it by just under 30 percent. The calculation is a simplification, because our wings have different profiles and aspect ratios. Aspect ratio means the ratio of wingspan to wing chord. The direction always holds, though: more area means flying earlier.

How Fast Are Our Aerofoils Hardboards?

According to the spec sheet, the Aerofoils Adventure eFoil Set reaches up to 50 km/h, while the Performance and Competition eFoil Sets reach up to 55 km/h. These top values apply to the whole system under good conditions; in everyday riding you'll usually go much slower.

Volume describes how much buoyancy the board itself has in the water. A lot of volume carries you at the start like a thick air mattress. Less volume feels more like a slim surfboard, but makes the board lighter and more agile once you're flying.

You only feel the 5 km/h difference between Adventure and Performance at full throttle. When cruising between 20 and 30 km/h, all three boards are fast enough. They differ far more in stability, agility and maximum rider weight.

If you're new to the sport, top speed barely matters. What matters more is a board that suits your weight and a wing that lifts off early.

Which Wing Makes You Faster?

Smaller front wings make you faster, bigger ones lift off earlier: according to our wing overview, the Freeride 1350 reaches up to 46 km/h and the Freerace 900 up to 50 km/h. The Easyride 2000, on the other hand, is built for early lift and plenty of stability, not for speed.

The reason is drag. A big wing produces a lot of lift, but slows you down more at high speed. A small wing slips through the water with less drag. In return, it needs more run-up and reacts more sensitively to your weight shifts.

The wing values in our wing overview apply to a typical rider. The board values show what the whole system can do at most, for example with a light rider, a sporty setup and flat water. For everyday riding, the wing values are the better reference.

The stabilizer is part of the wing system too. It's the small rear wing at the back end of the fuselage, the connecting rod at the bottom of the mast. It dampens pitching, the up-and-down movement of the board's nose. A smaller stabilizer makes the setup faster, but also more nervous.

If you already ride an Aerofoils eFoil: Many riders have to stand further and further forward at high speed, because the front wing produces more lift. A positive shim is a small wedge between fuselage and stabilizer. It reduces the downforce at the tail, the force with which the stabilizer pulls the tail down. That gives you more top speed and a more relaxed stance, but makes the board more sensitive, as we show in eFoil Stabilizer Angle of Attack.

Rule of thumb: Only switch to a smaller wing once you take off reliably, carve steadily and often ride at the upper end of its speed range.

What Determines Your Speed Besides the Wing?

Besides the wing, your weight, the riding mode and the conditions on the water decide how fast you actually go. Wind, waves and chop cost speed and control, while the difference between salt and fresh water hardly matters at all.

• Weight: More weight needs more lift. You take off later and reach top speed less easily. Check the maximum rider weight of your board.
• Riding mode: In the beginner mode, top speed is deliberately limited. Only the sportiest mode unlocks full speed; more on that in the section on riding modes and the speed limiter.
• Wind: Headwind slows you down and makes the board less steady. Tailwind pushes you, but often makes control harder.
• Chop and waves: Chop means short, irregular waves. They force you to slow down, otherwise the wing breaches or the board slams down.
• Salt or fresh water: Salt water is around 2.5 percent denser. In theory, that lowers your takeoff speed by only about 1 percent. You won't feel it.

If you already ride an Aerofoils eFoil, keep an eye on the display of your remote control. It shows your current speed in km/h. That way you quickly learn at what speed your setup is at its calmest.

How Does Your Riding Style Affect Battery Life?

You ride longest when you're flying and holding a calm cruising speed. High speed, constant full throttle, wind, waves and a higher weight all drain the battery faster. Surface riding also uses more energy than flying, because the board is being pushed through the water.

Our Endurance Battery delivers up to 120 minutes or up to 40 km on one charge, the Light Battery up to 60 minutes or 20 km. You reach these values with calm, steady riding.

The biggest lever is the difference between surface riding and flying. On the surface, the whole board sits in the water and pushes a bow wave ahead of it, like a boat. That takes a lot of power. As soon as you're flying, only the wing, mast and drive are in the water. Drag drops considerably, and you get much further on the same charge.

At the top end, there's a simple rule of thumb: the drag of wing, mast and drive grows with the square of speed. You know this from cycling: at double the speed, the headwind pushes about four times as hard. Anyone riding full throttle the whole session will therefore finish noticeably sooner than someone cruising relaxed.

How to get more ride time out of every charge:

• Take off promptly instead of staying on the surface for long.
• Ride most of the time at a cruising speed a little above takeoff speed.
• Use full-throttle stretches deliberately instead of riding them constantly.
• In wind and waves, prefer sheltered bays.

Pro tip: Always plan your way back with a reserve. Set off into the wind if you can, while the battery is full. Then the wind pushes you home when energy is running low.

Riding Modes, Power Levels and Speed Limiter: How to Control Your Speed

Our remote control offers three riding modes, ten power levels and a speed limiter, which you use to set acceleration and top speed. For beginners, these settings matter more than any top speed, because they make the board predictable and help avoid hard falls at high speed.

The three riding modes differ in responsiveness and speed limit:

Power levels divide the power range within each mode, a bit like gears on a bike. With Double Gears, ten levels become 20 finer ones. That helps when starting slowly and you want to control your takeoff.

The speed limiter sets a fixed upper limit for your speed, no matter how far you pull the trigger. It only works with GPS reception. In Gonna-Fly mode, it also limits acceleration.

How Fast Should You Ride as a Beginner?

In your first sessions, it's best to stay well below 30 km/h, because the goal is a controlled takeoff and a soft landing, not speed. If you ride too fast too early, you fall harder, lose confidence and end up taking longer until flying really clicks.

How to build up your speed step by step:

1. Start lying down and kneeling: Get used to throttle and steering on the surface in Gonna-Fly mode, without taking off.
2. Take off briefly, land right away: Build speed slowly until the board lifts, and ease off the throttle immediately.
3. Fly steadily at around 20 to 25 km/h: Hold your height, ride long straights and your first wide turns.
4. Switch to the next mode: Only once takeoff, turns and landing work reliably, try Nice & Smooth.
5. Increase speed in small steps: Use Double Gears and the speed limiter to work your way up to higher speeds gradually.

In the Aerofoils Academy in our app, you'll find tutorial videos and manuals for your eFoil.

How Dangerous Is a Fall at 40 km/h?

A fall at 40 km/h is much harder than at 20 km/h, because impact energy grows with the square of speed. Double the speed means about four times the energy. That's why we always recommend a helmet, and from sporty speeds on, an impact vest too.

At high speed, water no longer feels soft. You hit it flat and skid across the surface. An impact vest cushions the blow to your upper body. A water sports helmet protects your head from the board and from hitting the water.

Keeping your distance matters just as much. At 40 km/h, you cover around 11 meters per second. So keep enough distance from swimmers, jetties and boats that you can always get out of the way.

Our jet drive works with a propeller inside a closed housing, so there are no exposed blades. The board itself and the wing are still hard objects, though.

How Fast Are You Allowed to Ride? It Depends on the Water

There's no universal speed limit for eFoils. Which rules apply depends on the water you ride on and on who is responsible for it. Near the shore, at swimming areas and in harbors, stricter limits often apply, and on some waters motorized craft are banned entirely.

In Germany, for example, there are roughly three cases:

• Federal waterways: Large rivers, canals and many connected lakes belong to the federal government. The rules of the Waterways and Shipping Administration apply here. ELWIS, the administration's information service, gives an overview.
• State waters: Most lakes are regulated by the federal states with their own ordinances. District or municipal rules often come on top.
• Private waters and protected areas: On private lakes, the owner decides. In nature and landscape reserves, riding is often restricted or banned.

Other countries have their own systems. Before your first session on a new spot, ask the responsible authority, the water police or the local water sports club. They know the local rules best.

Important: Speed limits apply to you too, even though your eFoil is quiet and emission-free. Use the speed limiter to stay below the limit on your water, so you don't have to keep checking the display.

For registration, license requirements and local rules in Germany, we have a dedicated guide: eFoiling Regulations in Germany.

How Much Horsepower Does an eFoil Have? Reading Power and Units

According to the spec sheet, our drive units deliver a maximum of 5 kW, which is around 6.8 hp. That sounds like little, but it's enough for up to 55 km/h, because a flying eFoil has almost no board drag to overcome. Speed is mainly determined by the wing, weight and the efficiency of the drive.

The 5 kW apply to both drives, the Competition eDrive Unit 80 cm and the Hyperdrive ABS Jet Drive Unit 60 cm.

A jet ski needs much more power, because it pushes its hull through the water. An eFoil flies above the water and only has to pull wing, mast and drive through it. That's why far less power is enough for a similar cruising speed.

For conversion: 1 kW equals 1.36 hp. Power also matters for registration and licensing, because Germany has fixed horsepower thresholds for both. Which ones apply and what they mean for your spot is covered in our guide to eFoiling regulations.

If you ride abroad, you'll often see miles per hour, especially in the US and the UK:

Our Verdict

An eFoil is fast enough to get your pulse up, but its real strength is cruising between 20 and 30 km/h. That's where you fly steadily, save battery and stay in control. You get more speed mainly through wing, weight and riding mode, and the speed limiter keeps you within the rules on your water. Which board and wing suit your weight and your spot, our Board Match Quiz will tell you.
