Aerofoils vs. Lift Foils: Which eFoil Fits Your Water?

Quick Answer

Aerofoils and Lift Foils both build premium eFoils, but for different water. Lift Foils comes from the ocean in Puerto Rico and is built for wave riding. Aerofoils is developed and tested in European waters: lakes, the Baltic, the North Sea, the Mediterranean. If you want to ride waves, Lift is hard to beat. For everything else, we build the better-suited board.

We're not writing this comparison to make a competitor look bad. Lift Foils builds excellent eFoils, and in one discipline they're better than us. That's in this article just as much as the points where we come out ahead.

What we don't want to hear anymore is the shorthand "Aerofoils has a jet, Lift has a propeller." It's wrong, and we clear it up in the very first section.

Aerofoils and Lift Foils at a Glance

The key differences in one table. Everything else is covered in detail in the sections below.

The battery figures are manufacturer specs measured under each brand's own conditions. Measuring in the ocean means measuring against swell and current, so a direct comparison of the two numbers doesn't hold up.

What's the Most Important Difference Between Aerofoils and Lift Foils?

The most important difference isn't the drive, it's the water each board was built for. Lift Foils develops and tests on the open ocean in Puerto Rico, where one- to two-meter swell is the norm. We develop and test in Europe: on lakes, on the Baltic and North Sea, in the Mediterranean.

That sounds like a footnote. It's actually the decision everything else follows from.

Whoever builds a product builds it for the conditions outside their own door. The people who design, test, and ride at Lift go out in swell. Their boards are thought through from wave riding, and even the entry models trace back to a surfboard shape. For the ocean, that's exactly right.

Only most eFoil riders don't ride the ocean. They ride a lake with a light breeze, the Baltic Sea with short, choppy waves, a bay on the Mediterranean, a river. For that water, a board built around wave riding isn't the obvious answer, and that's exactly where we come in.

One water decision drives everything else. Lift Foils develops, tests, and rides on the open ocean in Puerto Rico. Aerofoils does the same on European lakes and coastal waters. Both build premium eFoils, just for different water, and that single decision shapes the drive, the mast, and the equipment on both boards.

Does Lift Foils Have a Propeller or a Jet?

A propeller, in three variants. LCS is Lift's quick-release drive system: it lets you click a propeller attachment in and out of the board without tools. Through it, Lift offers a folding propeller, a fixed propeller, and a third attachment Lift itself calls a "jet." Structurally, that third attachment is a shrouded propeller. You buy the drive as an attachment, and you can swap it. We don't offer that choice, and that's not an oversight, it's the point.

The difference is attachment versus architecture.

At Lift, a drivetrain built for propellers optionally gets a shroud around that same propeller. That improves safety, and as a swappable option it's a sensible piece of engineering. It isn't a jet in the fluid-dynamics sense: the shroud isn't an engineered nozzle duct, it's a housing around a propeller blade. It costs the propeller some of its efficiency without reaching the efficiency of a true jet geometry.

For us, the jet isn't an option, it's the foundation. The board, the fuselage, and the mast were designed around the jet from the first sketch, not the other way around. We invented jet propulsion for eFoils and haven't built anything else since. Nine years of development work go into a single drive concept instead of three.

That's why a retrofitted attachment doesn't deliver the same performance as a drive that was engineered as a jet from day one. At Lift, that variant stays a secondary line, because their development focus sits on propellers, for the same reason as above: on the ocean, the propeller is the right choice.

Attachment versus architecture, in one line. Lift sells the jet as one of three swappable attachments on a propeller-based drivetrain. For us, the jet is the drivetrain, engineered into the board from the start rather than bolted on afterward.

Is a Jet More Efficient Than a Propeller?

No. A propeller is physically more efficient than a jet, it converts more electrical power into thrust. That's not a marketing question, it's fluid dynamics, and we'd rather say it ourselves than have it pointed out to us. The jet earns that disadvantage back through the design of the whole board, not through the drive alone.

What you get in return are three things that matter more day to day than the last percentage point of efficiency:

• No exposed blades. On a folding or fixed propeller without a guard, a spinning blade is exposed. Not so on the jet, and you can't accidentally set it up the wrong way either, since there's no other variant.
• No torque on the board. A propeller generates torque under acceleration that can tip the board sideways. Especially during the learning phase at low speed, that's the moment beginners fall off. The jet doesn't have that behavior.
• Smooth power delivery. Thrust builds evenly instead of hitting all at once. That's why schools work with our boards.

The order matters here: the efficient option is the open propeller. As soon as a shroud sits around it that isn't engineered as a nozzle, that advantage is gone, and you end up with neither the propeller's efficiency nor the flow of a true jet.

In numbers: we quote up to two hours of ride time for the Endurance battery at 2.23 kWh, Lift quotes up to 90 minutes for the Gen5 battery at 2.2 kWh. Both are manufacturer specs measured under each brand's own conditions, and the conditions here genuinely aren't the same. Measuring in the ocean means measuring against swell and current.

Efficiency versus real-world tradeoffs. A propeller is physically more efficient than a jet. At Aerofoils, the jet isn't an option, it's the design foundation of the whole board. A propeller wins on raw efficiency; the jet earns it back through safety, the absence of torque, and smooth power delivery.

Which eFoil Is Better on Waves?

Lift Foils. If you're buying your eFoil to ride waves, riding in Portugal, Fuerteventura, or Bali, and using the drive mainly to catch the wave, Lift is the right choice. The folding propeller has the least drag when riding down a wave, the wing lineup goes all the way to downwind and prone wings, and the boards are shaped around exactly that feel.

That's not a polite gesture, it's the honest consequence of the first section: nine years of development in wave-riding water show in the product.

Our boards can also be ridden on waves. The slim diameter of the jet housing creates so little drag that you don't need a folding propeller for it. But if the wave is the main reason you're buying, buy the board that was built for it.

Which eFoil Is Better on Lakes, the Baltic Sea, and the Mediterranean?

Ours, because it was developed for it. Inland and coastal waters in Europe mean short, choppy chop instead of long swell, shallow water, shifting wind, and often a slipway instead of a beach. Our entire test program runs on these conditions, and three design features come directly from it.

The 80 cm carbon mast. It's standard on our boards, and we're the only manufacturer that can fully exploit that length. A longer mast keeps the wing deeper in the water. In choppy conditions, that means the wing runs below the surface disturbance instead of inside it. And in tight, steep turns you can carve further before the wing breaks out. Lift's entry model comes with a 28-inch aluminum mast; upgrading to carbon is an accessory purchase in the low four figures.

The enclosed drive in shallow water. Seagrass, algae, and fishing line are the norm on lakes and in the Baltic Sea. A spinning blade eats that material and winds it up. Our jet doesn't: the intakes are small enough that seagrass gets guided around the outside of the housing instead of getting sucked in. To be fair, very small debris like sand or gravel can get drawn into the impeller, so anyone launching off a shallow, sandy bottom should keep that in mind.

Riding modes with adjustable power and speed limits. On European waters you rarely ride alone, sailors, anglers, residents. You can cap power before handing your board to someone else, and the limit actually holds.

On waves, Lift Foils wins. On the water most riders actually see, we do. On European lakes, the Baltic, North Sea, and Mediterranean, Aerofoils is the better fit, thanks to the standard 80 cm carbon mast, the enclosed drive around seagrass and algae, and the adjustable power limit.

How Fast Can I Get Spare Parts?

With us, typically within 48 hours. Aerofoils is a German manufacturer with a central warehouse in Europe: spare parts sit where our customers actually ride, and support speaks German and English. Lift Foils ships from Puerto Rico. Once a part has to fly out of there and clear customs, that can quickly turn into several days to weeks.

That's the point that never shows up on a spec sheet, and it decides the season. An eFoil waiting on a spare part in July isn't an eFoil, it's a piece of furniture. Anyone who only rides from May to September loses a fifth of their season to three weeks of downtime.

There's also who's on the other end of the line: with us, you reach the manufacturer directly, not a layer in between. To be fair, Lift has stayed owner-operated and has support that's known to be fast and competent. The distance is still the distance.

Where the parts sit decides your season. Aerofoils ships spare parts from a European central warehouse, typically within 48 hours, with German- and English-speaking support straight from the manufacturer. Lift Foils ships from Puerto Rico. Across a May-to-September season, that difference decides how many days you actually get on the water.

How Do the Mast and Wings Differ?

We ship the 80 cm carbon mast standard; Lift's entry model comes with 28-inch aluminum. The wing lineup flips the picture: Lift offers the wider selection, we offer the more clearly organized one.

Carbon is stiffer and lighter than aluminum. Stiffer means your weight shifts reach the wing without delay. You don't feel that as a number, you feel it as directness.

Our wing lineup is built around three riding styles:

• Easyride 2000 × 510, the largest wing in the lineup, mainly for schools and riders over 100 kg. It lifts off earliest and forgives the most.
• Freeride 1350 × 400 and Freeride 1100 × 380, early lift, calm handling, forgiving. The starting point for anyone new to eFoiling.
• Freecarve 1250 × 270 and Freecarve 1000 × 270, narrower, eager to turn, for riders who want to carve tight.
• Freerace 900 × 300, the fastest wing in the lineup, for experienced riders.

Lift has built a broader range over the years, all the way to wings for downwind and prone surfing without a drive. If you want to use your board without power too, you'll find more choice there.

Does a Jet eFoil Hold Up in Racing?

Yes, and it's the best evidence that jet technology isn't just a beginner solution. Our own race results back this up. Team rider Clemens Kresser regularly makes the podium on the Competition. He took second place in Dubai and second in Abu Dhabi. At the SFT E-Foil World Cup Munich 2026 he placed second in the Pro class and won the Masters category. At Lake Garda, he made the podium again in the Pro final.

He races the Competition at 73 liters, the same drive concept as every one of our boards, just tuned to the smallest volume and fastest wing. A racing calendar across multiple continents is the toughest durability test there is for an eFoil.

To be honest: at Lake Garda, riders on Lift Foils won. The world's top field rides both brands, and anyone claiming otherwise hasn't watched a race. The point is a different one: holding your own on a tight course against the world's best isn't hobby equipment.

What Comes Standard, and With Which Brand?

For us, a carbon board, the 80 cm carbon mast, a remote control with a color display, and a properly sized battery are all standard equipment. At other manufacturers, some of that sits on the upcharge list or belongs to a more expensive model line. To be fair, Lift also ships its boards fully equipped; the color display is standard on the Lift5, though the LiftX gets a monochrome one instead.

On top of that, we offer a few points that rarely show up on a spec sheet:

• Reverse gear. Worth its weight in gold at the dock, at a buoy, and when freeing yourself from shallow water. No other manufacturer offers it as standard.
• Automatic battery discharge. The system brings the battery to the right charge level for storage on its own. If you store it over winter, you don't have to think about it.
• Three riding modes with adjustable limits. The reason schools work with our boards.
• Two radio receivers. Redundancy on the one connection that can least afford to fail.
• Two battery options. Light at 1.13 kWh and 8.8 kg for anyone who has to carry it; Endurance at 2.23 kWh and 13.0 kg for long sessions. The light battery charges to 80 percent in 50 minutes.

What Does Lift Foils Do Better Than Aerofoils?

Lift is stronger on modularity, and it's the better choice on waves. The LCS system lets you click the drive in and out without tools, the attachment swaps with a locking button, and the board is ready in under a minute. If you travel a lot, disassemble often, and switch between riding styles, you feel that at every setup.

• Assembly in under a minute. No tools, no cabling to fuss with. Anyone who's ever still been assembling their board while everyone else was already in the water knows what that's worth.
• Choice of drive. Folding propeller, fixed propeller, or shrouded variant on the same board, depending on the water and the day.
• Wing lineup. One of the broadest on the market, all the way to downwind and prone.
• Reach. Especially strong in the US. More riders means a bigger used market, more third-party accessories, and more people at the spot who can help.
• Blowfish. Lift's inflatable stability rails are a mature learning aid; inflated to 7 PSI, they support riders up to 129 kg. We have a comparable concept in the Aeroloop (+60 liters), but Lift was early with the idea.

One limitation belongs here too, and it hits exactly our kind of water: the click system depends on clean contact surfaces. Salt crystals after a Baltic Sea session or sand from the beach settle into the fitting, and then the connection stops locking cleanly. If you ride that kind of water, you have to consistently rinse the contact surfaces with fresh water, or the advantage turns into a hassle.

What Does Aerofoils Do Better Than Lift Foils?

We build the board that fits European waters, and we build only one. The jet isn't an option bolted onto a propeller drive, it's the foundation of the design. On top of that: the standard 80 cm carbon mast, spare parts from the European central warehouse within 48 hours, and standard equipment that doesn't need an upcharge list.

The core of it in one sentence: Lift builds the best board for waves. We build the best board for everything else, and that's the larger share of the water out there.

One board each, and one clear answer. Want to ride waves? Buy Lift Foils. Riding lakes, the Baltic, the North Sea, or the Mediterranean? Aerofoils is the better-fitting board, developed, tested, and equipped for exactly that, with spare parts sitting in Europe.

Who Fits Which eFoil?

Aerofoils fits you if:

• You ride lakes, the Baltic Sea, the North Sea, or the Mediterranean. That's exactly what the board is developed and tested for.
• You're a beginner, or you hand your board to other people. No torque on takeoff, no exposed blades, adjustable power limit.
• You run a school, a resort, or a rental operation. Capped power, a protected drive, and two hours of ride time matter every single day in commercial use.
• Short service turnaround matters to you. German manufacturer, European central warehouse, German- and English-speaking support.
• You ride water with seagrass, algae, or boat traffic.
• You want to choose between a hardboard and an inflatable. The Airfly at 150 liters and the Hyperfly at 230 liters run the same drive technology.

Lift fits you if:

• You want to ride waves. That's what Lift is built for, and there it's hard to beat.
• You come from surfing, kiting, or foiling and want a board that feels like surfing.
• You rebuild your setup constantly and want to switch between jet, folding, and fixed propeller.
• You ride in the US. That's where Lift's service network is densest.
• You value a large used and accessory market.

Which Aerofoils model? As a rule of thumb, aim for roughly one liter of board volume per kilogram of body weight; if you're just starting out, lean toward more. Our Board Match Quiz walks you through it in a couple of minutes if you want a direct recommendation.

Can You Retrofit the Drive Concept?

At Lift, yes; with us, no. Lift sells jet, folding, and fixed propeller as swappable attachments. For us, the jet is integrated into the mast and fuselage and was developed together with the board from the start; it can't be swapped out, and that's the price of it being no compromise. Wings, batteries, and remote controls can be swapped on both systems.
