North Sonar Pump Series Front Wing
Purpose-built low-speed efficiency for relaxed pumping, long glide, dock starts, and flatwater paddle-ups—with P1800 and P2050 options matched to rider weight and experience.
The North Sonar Pump Series Front Wing is designed to maintain flight with very little rider input. Available in P1800 and P2050, these high-efficiency, low-speed front wings favor a relaxed pumping cadence, predictable lift, and dependable glide instead of requiring an aggressive, high-frequency pump. A stiff high-modulus carbon prepreg construction provides direct response, while the broad, efficient outline helps riders stay on foil through flatwater pumping, dock starts, and SUP paddle-ups.

Why You’ll Love the North Sonar Pump Series
Long-Duration Pumping
The Pump Series is designed to maintain flight with very low power input, helping riders pump longer without relying on an exhausting, high-frequency cadence.
Low-Speed Flight
The lift-focused foil sections allow the wing to keep flying at slower speeds, giving riders more time to correct their rhythm before the foil drops off.
Predictable Response
A stiff high-modulus carbon laminate creates reliable feedback and controlled energy transfer, making pumping inputs feel direct and repeatable.
Manageable Maneuverability
Despite their generous area and span, both wings are shaped to remain intuitive and manageable when turning around docks, navigating flatwater, or setting up another pumping run.
Designed for Pumping Efficiency
Relaxed Pumping Cadence
The P-Series favors a smooth, endurance-oriented rhythm. Riders can focus on efficient technique and consistent movement instead of constantly fighting to keep the foil flying.
Efficient High-Aspect Outline
Wingspans of 1300 and 1400 mm create strong glide and help conserve momentum between pumping inputs, while still providing predictable lateral stability.
Low-Speed Lift
The foil sections are optimized for lift and efficiency at the lower end of the speed range, supporting dock starts, flatwater pumping, and SUP paddle-ups.
Purpose-Built Performance
This is a specialized Pump Series rather than a general-purpose high-speed wing. Its strengths are endurance, low-speed flight, pumping rhythm, and easy glide.
Key Features
High-Modulus Carbon Prepreg
The stiff high-modulus carbon prepreg construction helps minimize unwanted flex, delivering precise feedback and predictable energy return through each pumping cycle.
High-Efficiency Low-Speed Design
The wing profile is tuned to maintain lift and glide at slower speeds, helping maximize pump duration and making small technique corrections less punishing.
Titanium Mounting Screws
North supplies titanium front-wing screws for a strong, corrosion-resistant connection to a compatible Sonar fuselage.
Endurance-Focused Cadence
The Pump Series is designed around a controlled and sustainable pumping rhythm, reducing the fear of immediately dropping off foil when cadence slows.
Two Rider-Specific Sizes
Choose the P1800 for riders under 85 kg (187 lbs) who want a slightly smaller, more responsive wing, or the P2050 for riders over 85 kg (187 lbs) and newer pump-foil riders seeking more lift.
Sonar Modular Platform
Both sizes connect to the North Sonar modular foil system and can be paired with North’s Glide Series stabilizers for a complete pump-focused setup.
Performance Feel
Smooth and Predictable
The foil delivers progressive lift and a stable platform, allowing riders to settle into a repeatable pumping rhythm instead of reacting to abrupt changes.
Effortless Glide Between Pumps
The wide span helps preserve momentum during the recovery portion of each pump, making it easier to cover distance with fewer unnecessary movements.
Low Stall Speed
The Pump Series remains supported at low speeds, giving riders extra time to correct technique and continue flying when their cadence becomes less precise.
Size-Dependent Agility
The P1800 feels more compact and responsive, while the P2050 emphasizes maximum lift, stability, and low-speed support for larger or less experienced riders.

Size guidance: North recommends the P1800 for riders under 85 kg (187 lbs). Choose the P2050 if you weigh more than 85 kg (187 lbs) or are newer to dock starts and flatwater pumping and want additional lift and low-speed support.
Recommended Sonar Stabilizer
Recommended: Glide S192
The North Sonar Glide S192 Stabilizer is the recommended all-around tail for both P1800 and P2050. It provides efficient pumping, effortless glide, low-speed support, and a stable, predictable platform for intermediate riders and pump-foil progression.
North item number: 85004.240102
Advanced Alternative: Glide S142
The North Sonar Glide S142 Stabilizer offers a faster, more responsive, and more maneuverable feel. It requires more precise technique and energy from the rider, making it better suited to experienced pump foilers.
North item number: 85004.240099
Windance recommendation: Start with the S192 if maximum pump duration, stability, and low-speed support are your priorities. Choose the S142 only if you already have efficient pumping technique and want a faster, looser, more responsive setup.
P1800 or P2050?
Choose the P1800 If…
- You weigh less than 85 kg (187 lbs)
- You already have basic pumping or dock-start technique
- You want a slightly faster and more responsive feel
- You value maneuverability as well as endurance
- You can generate enough initial speed to lift onto foil
Choose the P2050 If…
- You weigh more than 85 kg (187 lbs)
- You are newer to pump foiling or dock starts

North Sonar Pump Series FAQ
What is the Sonar Pump Series designed for?
The Pump Series is designed for flatwater pumping, dock starts, and SUP paddle-ups. Its low-speed efficiency helps riders maintain flight with less power input.
Which size should I choose?
North recommends the P1800 for riders under 85 kg (187 lbs). The P2050 is intended for riders over 85 kg (187 lbs) or newer pump-foil riders who benefit from additional lift and low-speed stability.
Which stabilizer is recommended?
The Glide S192 is the recommended default for both front wings because it provides stable, efficient pumping and strong low-speed support. The smaller S142 is an advanced alternative with a faster, more responsive feel.
Can the Pump Series be used for wing foiling?
The P1800 and P2050 are purpose-built for pumping, dock starts, and paddle-ups rather than general wing-foil freeriding. Riders seeking a broader wing-foiling speed range should consider a North MA or SF front wing.
Are mounting screws included?
Yes. Both P1800 and P2050 include North Screw Pack E with M8 × 33 mm titanium front-wing screws.
Is this a complete foil?
No. The listing includes the selected front wing, its cover, and mounting screws. A compatible Sonar mast, fuselage, stabilizer, board connection, and foilboard are sold separately.
Why Choose the North Sonar Pump Series?
The North Sonar Pump Series is built for riders who want to spend more time flying and less energy fighting to stay on foil. With low-speed lift, an endurance-focused cadence, high-modulus carbon prepreg construction, and two rider-specific sizes, the P1800 and P2050 provide a dedicated platform for flatwater pumping, dock-start progression, and SUP paddle-ups.
