FUSION ALLOY MAST FOIL – Only Mast 40cm 70cm 90cm The Fusion Alloy mast is constructed from aircraft-grade extruded aluminum, resulting in an incredibly rigid and hydrodynamic structure. Helicoil inserts prevent salt water corrosion at the screw connection points. The mast integrates seamlessly into all 9cm industry standard foil boxes. Only the mast in the first picture is sold here. The other pictures are for illustration purposes only!!!

SONAR CARBON FUSELAGE Foil Accessory Our high-strength pre-preg carbon chassis is strong, durable, and corrosion-resistant, weighing about 50% less than the alloy version at the same strength and stiffness. The shorter C600 chassis improves pumpability and provides a sporty feel with earlier starts. The more forgiving longer C700 chassis is ideal for wing foiling or learning to foil, offering greater stability and more control. The agile C650 is not as radical as the C600, but a step up in terms of freedom compared to the 700.

SONAR FUSELAGE Foil Accessory The hydrodynamically optimized shape of the Sonar chassis ensures minimal resistance. The chassis is precisely CNC-machined from 6061-T6 aircraft aluminum with an anodized finish and structurally engineered fasteners designed for durability. The shorter A600 chassis enhances pumpability and provides a sporty feel with earlier take-offs. Our longer A700 chassis offers a smoother, more stable ride across all foil disciplines. The forgiving length of 700 mm improves stability in combination with any wing and is ideal for learning to foil. The longer chassis delays the pitch moment, giving you more time to react. Equipped with GeoLock, a unique conical geometry locking connection between the mast and chassis for more efficient load transfer and a more durable connection. Compatible with all Sonar masts.

SONAR HA High Aspect Front Wing The Sonar High Aspect Front Wing Series is designed for maximum speed and efficiency across a variety of disciplines – from wing foiling to prone foil surfing. With this wing type, you need minimal pumping effort and power to glide. The shorter profile depth defines the profile strength, and with a thin profile, there is less drag. The wingspan provides stability and a slightly larger turning radius than a wing with a lower aspect ratio of the same size. The wingtips are refined to ensure there is no ventilation during peak exceedances, giving you the ability to take tighter turning radii at higher speeds without losing speed.

Sonar AF Board Adaptor Foil Accessory The sonar foil system is connected to the board with a lightweight, CNC-milled aluminum board adapter, featuring a conical geometry locking connection that connects to the mast and merges the board adapter and the mast into a single unit. This ensures optimal load transfer and a stronger, more direct feel, as well as precise steering impulse behavior during foiling. FE analysis allows us to increase strength in areas with the highest stress loads and reduce unnecessary weight in areas with lower loads. The system features a strong geometry locking connection for better energy transfer and a more direct feel.

SON OF Foil Mast Our refined Aluminium Foil (AF) profile offers the best balance between low weight and increased strength for higher loads. The AF72 mast is ideal for flatter water and surf foiling. The AF8 is the perfect beginner size for wing foiling. The AF85 performs in all disciplines and is more forgiving in rougher conditions. The AF85 and AF95 give you more height to cross waves or make tight turns. The 55cm AF mast is for extremely shallow waters. The Sonar mast features our unique GeoLock conical geometry locking system. Designed for strength and stiffness, GeoLock provides a more effective load-bearing connection between the mast and the fuselage that connects them, making them feel like one piece. Screws engage in the GeoLock, allowing load transfer across the entire cross-section of the mast profile and enabling more efficient load distribution and a secure connection that lasts. NOTE: The AF mast does not have an integrated foil board mounting plate. To mount it on your foil board, you will need the AF Board Adapter, which is available separately or included in all Sonar AF and Prime Editions.

SONAR-HM High Modulus Carbon Mast Incredibly thin. Impressively fast. We have reduced the thickness of the submerged part of our new high-modulus prepreg carbon masts by over 15% compared to our standard carbon masts, while simultaneously increasing both bending and torsional stiffness. The HM80 is preferred for disciplines without wind power – surf foiling, pumping, and downwind. The shorter line length across the entire mast length reduces drag and increases maneuverability. This results in more glide, more efficient pumping, and faster turns. The HM85 covers all disciplines, with a focus on wing foiling. Wind-powered disciplines require edging against the wind to generate propulsion. Part of this propulsion comes from the front wing, another from the mast. To deliver this drive efficiently, the line length in the submerged part of the mast is slightly longer. It increases towards the mast tip to maximize stiffness without increasing drag, as this part of the mast is out of the water when foiling. A more efficient underwater shape means less drag and thus higher and more easily achievable top speeds. Ventilation at the mast is now a thing of the past. We have paid special attention to this detail, so that regardless of sea conditions, ventilation at the rear part of the mast is significantly reduced. The HM105 is optimized for racing. The thickness of the submerged part of the mast is another 1 mm thinner than that of the HM80 and HM85 to achieve maximum top speed. Therefore, this mast is not suitable for jumping. As with the HM85, the line length in the submerged area is designed to provide good lift drive, while the line length above the waterline increases to maximize stiffness. A more efficient underwater shape means less drag and thus higher and more easily achievable top speeds.

SONAR S Freeride Stabilizer Exceptional gliding. Our new thinner profiles and higher aspect ratio in the carbon stabilizers offer reduced drag and a more efficient contour. The S270 is your all-rounder for kite, wing, and surf performance, providing optimal balance, speed, efficiency, and control. Combine the S210 with a smaller front wing for high-speed performance and a more agile feel. Combine the S320 with a larger front wing for early planing, more balance, and stability.

SONAR S Surf Stabilizer The Sonar S Surf Stabilizer has a lower stall to complement the SF front wings. Its moderate wingspan creates a sufficiently high aspect ratio for efficient pumping while remaining compact for responsiveness in turns. The minimally curved contour enhances performance at low speeds and effectively reduces the fuselage length compared to curved stabilizers. The wingtips bend upwards to provide directional stability, instilling confidence during takeoff and providing grip in turns. Advanced riders seeking a looser feel can remove the wingtips using the dotted guideline graphic to create a completely flat stabilizer.

SONAR S High Speed Stabilizer Flat, loose, and even faster – the new S-Stabilizer is a high-speed upgrade for the Sonar foil system for experienced riders. As we have expanded our front wing range, we had to match the lift of the front wing with the stabilizer. While your front wing generates vertical lift, your stabilizer acts downward, preventing the front wing from diving. A larger stabilizer means more pressure on the front foot, while a smaller stabilizer means less pressure on the front foot. The North stabilizers are mounted above the fuselage, which avoids turbulence in the flow field of the front wing and allows for a smoother ride. This upper mounting also gives the rider an early warning of exceeding the limit – the stabilizer breaks the water surface first, giving you a better chance to recover before your front wing comes too high. Like the front wings, all Sonar stabilizers are made from prepreg carbon, ensuring optimal stiffness and direct performance. The thin profile reduces drag, while the material properties maintain structural integrity and stiffness. Stabilizers have a significant impact on performance. As you progress to smaller wing sizes, we recommend switching to a smaller stabilizer to be more maneuverable. Experienced riders will really feel the difference. A new tail wing can have a big impact on your style.
