How to Read eFoil Specs: The Metrics That Actually Matter

Most efoil specs sheets look identical until you start comparing line by line, and that is where buyers get burned. A spec sheet is a marketing artifact, not a technical document, until you know which numbers actually predict the ride. After running hundreds of hours on the water with ASUFUN engineers, the metrics that consistently matter are motor thrust in kilograms, battery capacity in watt-hours, total system weight, and top speed adjusted for rider load. Everything else is decoration.

Here is the framework our team uses internally when evaluating efoil specs for any new system, from a beginner-friendly Core build to a high-output Power Max rig. The four questions below separate spec sheet fiction from usable performance, and they apply whether you are buying in the USA, Europe, or Australia.

• Thrust vs rider weight: A motor that delivers 35 kgf of thrust feels very different to a 65 kg rider than to a 100 kg rider. Always compare thrust to your all-up riding weight, not to the headline figure.
• Battery watt-hours, not minutes: Runtime numbers quoted by manufacturers vary by 40-60% depending on throttle profile. Watt-hours are honest: divide by average draw to estimate session length.
• Total system weight: Board + motor pod + battery, with no rider. This is the number that decides how the board handles at low speed and how easy it is to lift onto a roof rack.
• Ingress protection: IP68 is the only rating that holds up to saltwater submersion. Anything below that is freshwater only.

If a brand does not publish those four numbers clearly, treat the rest of the spec table as decoration. In our testing across Lake Tahoe, the Mediterranean, and the Gold Coast, the boards that publish honest thrust and watt-hour data consistently outperform the ones that lead with vague ride time claims. For a complete walkthrough of how motor power translates to thrust on the water, see our efoil motor power guide.

Complete Spec Table: ASUFUN Power Max vs Core vs 8kW Board

This is the table our support team sends to riders who ask the inevitable question: how do the three ASUFUN efoil specs compare? The numbers below are pulled from in-house bench testing, not from marketing copy, and they reflect what each board actually delivers out of the box with a fresh battery and a 75 kg rider on flat water.

Three patterns jump out immediately. The ASUFUN Power Max is optimized for efoil performance over distance thanks to its user-swappable battery cell design. The Core wins on peak thrust per kilogram, which is why beginners find it so forgiving. The 8kW Electric Hydrofoil Board is the workhorse, with a 120 kg load rating and a 50Ah battery built for commercial use and heavier riders in USA surf shops, EU rental fleets, and Australian tour operators.

Use this efoil technical specifications table as the baseline, then read the sections below for the reasoning behind each row. ASUFUN publishes the same data our engineers use so that you can spec the right board on paper before paying a dollar.

eFoil Wing Size: How Front and Rear Wings Affect Handling

Efoil wing size is the single biggest lever you have over how a board feels on the water, and it is also the spec most beginners misunderstand. Front wing area (measured in square centimeters or square inches) determines low-speed lift, stability, and the minimum take-off speed. Rear wing area balances the front wing and adds directional stability without adding too much drag. Together they form the personality of the board.

In our testing on flat lakes in Texas and choppy bays in Sydney, the rule of thumb below held true across every rider we measured. Bigger wings lift heavier riders and deliver smoother rides; smaller wings reward aggressive carving but punish you in chop.

• Beginner wing size: 900-1100 cm² front wing. This is the training-wheel range. Lower take-off speed, more forgiving balance, easier to recover from small mistakes.
• Intermediate wing size: 700-900 cm² front wing. The sweet spot for most riders, especially those riding 50-90 kg and using the ASUFUN Core or Power Max at moderate throttle.
• Performance wing size: 500-700 cm² front wing. Carving, top-speed work, and experienced riders only. Marginal improvements on lift efficiency but a big drop-off in low-speed stability.

Rear wings are typically 30-50% of the front wing area, and they are where you tune the boards directional feel. A larger rear stabiliser makes the board feel planted at the cost of carving agility. A smaller rear lets the board pivot faster for surf-style turns. ASUFUN engineers ship a balanced rear wing by default on every board, then offer alternate sizes as riders progress from session-one basics to third-year performance work. For a deeper look at how wing geometry maps to actual riding style, the efoil speed and performance guide covers the full propulsion chain.

eFoil Propeller Size and Pitch: Choosing the Right Prop

The efoil propeller is where the motors rotational energy actually becomes forward motion, and picking the right one matters more than most buyers realize. Propeller size (diameter in millimeters) and pitch (the angle of attack, also in millimeters) together determine how the motors power curve translates into thrust at a given speed. Diameter affects maximum thrust; pitch affects cruise efficiency.

Three-blade designs are now the standard across ASUFUN, Lift Foil, Waydoo, and Fliteboard, and they hold up better to minor water impacts than two-blade alternatives. Most props fall between 165 mm and 200 mm in diameter. Pitch ranges from about 5.5 to 7.5 inches, with higher pitch favoring top end and lower pitch favoring hole-shot acceleration.

• Small prop (165-175 mm diameter, low pitch): Best for beginners. Quick throttle response, easy to control at low speed, gentle on the battery.
• Medium prop (180-190 mm diameter, mid pitch): All-round choice for the ASUFUN Core and most riders between 65-90 kg. Balanced cruise efficiency and acceleration.
• Large prop (195-200 mm diameter, high pitch): Maximum thrust for heavy riders or for towing setups that ride the 8kW Electric Hydrofoil Board in commercial rental fleets.

Efoil propeller size also interacts with efoil wing size in a non-obvious way. A small wing paired with a large prop produces nose-up torque that shows up as board oscillation at low speed; pair it with a small prop and the same setup feels locked in. ASUFUN engineers test every board with multiple prop options before shipping the production calibration, so the prop on your board out of the box is the one that matched the wing choice in our internal runs. Riders swapping to aftermarket props should keep that pairing in mind rather than chasing a single performance dimension.

eFoil Board Dimensions: Length, Width, Volume, and Weight

Board dimensions define how a board floats when the motor is off, how it lands when a jump goes wrong, and how stable it feels at the moment of take-off. The four dimensions every buyer should compare are length, width, volume in liters, and total system weight. Efoil technical specifications sheets often list the board alone, but the real spec is board plus motor pod plus battery, because that is what you carry to the water.

Length ranges from about 5 ft 0 in (150 cm) for performance shortboards to 6 ft 4 in (190 cm) for beginner-friendly platforms. Width runs from 24 to 30 inches. Volume scales roughly with length: a 5 ft 5 in beginner board usually sits around 90-110 liters, while a 5 ft 0 in performance board sits closer to 60-70 liters. Total system weight (board, motor pod, mast, battery) is the number most brands prefer to omit; ASUFUN publishes it because it changes how the board rides when the foil is out of the water.

For riders over 85 kg or anyone starting from zero, the longer, wider, higher-volume platform is the safer choice. It paddles like a paddleboard when the motor is off, which matters for safety in a stalled-foil scenario. The ASUFUN full carbon fiber board is the premium choice, pairing a 5 ft 5 in length with a sub-15 kg system weight that experienced riders in Europe and Hawaii have been switching to for travel-friendly foil sessions. For riders in the USA sizing up their second board, the volume-to-weight ratio is usually the deciding factor, not the length alone. See our efoil weight and board-size guide for the full matching framework.

eFoil Specs vs Competitors: Lift Foil, Waydoo, and Fliteboard

Side-by-side efoil specs with competitors is where the conversation gets honest, because the same motor power can mean very different things in real use. The three brands most riders compare against ASUFUN are Lift Foil (USA), Waydoo (China / global), and Fliteboard (Australia). Below is what the published spec sheets actually show when you align them on the same columns.

Two patterns emerge from this side-by-side. First, on raw thrust and watt-hours, ASUFUN, Lift, and Fliteboard are within striking distance of each other, which means the headline efoil specs are not where the differentiation lives. Second, ASUFUNs replaceable battery design is genuinely different: Lift and Fliteboard ship with sealed packs, which means hours-long charging and pack replacement costs in the four-figure range. In our testing on rental fleets in Spain and Portugal, the ability to hot-swap cells is the single biggest operational advantage for anyone running a guided session or a B2B rental operation.

For a deeper side-by-side that includes price, customer service, and warranty terms, our ASUFUN vs Lift Foil vs Waydoo vs Fliteboard comparison is the most complete breakdown published in 2026.

How to Use Specs to Choose Your Perfect eFoil

The right way to use efoil specs is to start with your body weight, then with your realistic session length, and only then look at top speed. Most riders do the opposite, which is why so many first boards end up wrong. Below is the decision tree our team walks every new rider through during pre-sale consultation.

1. Step 1: Get honest about riding weight. Add your body weight, wetsuit, life jacket, and any gear. Round up 5 kg for safety margin.
2. Step 2: Decide on session length. A 60-minute social ride on flat water needs far less battery than a 3-hour open-water tour. The Power Max Battery is the right call for the second case because the cells are replaceable.
3. Step 3: Match wing size to skill level. Beginners need a 900-1100 cm² front wing regardless of body weight. Experienced riders can size down.
4. Step 4: Choose prop and mast together. A 75 cm mast suits lakes and small chop. A 65 cm mast rewards surf and chop riding. Props scale with rider weight, not skill level.
5. Step 5: Compare total cost, not sticker price. Battery replacement, warranty service, and IP rating all fold into the lifetime cost. ASUFUN publishes efoil specs and pricing together so that buyers can see the trade-off in one place.

If you are still circling between two or three systems, our team will spec-match you to a board based on the answers above. Riders in the USA, Europe, and Australia all use the same decision framework, and ASUFUN engineers review the order before it ships so the configuration matches the local water conditions. Whether that ends up being the Core for a learning rider, the Power Max for a range-focused enthusiast, or the 8kW Electric Hydrofoil Board for a heavier rider or commercial operator, the path there is the same five steps.
