X-15 Wing

One-Design Wingfoil Racing

There are many popular one-design classes in both sailing and windsurfing. But, until now, there have not been any one-design wingfoil classes. So here we are. Together, Starboard and FreeWing have stepped up to the plate to introduce one-design wingfoil racing.

Why one-design racing though? Well, it’s a whole lot more fun when everyone is in the same “race car”! One-design racing is popular, largely because homogenous equipment inherently introduces elements of fairness. That means no decisions and no second-guessing. And the gear stays the same for longer so you don’t have to update it every year – avoiding the much criticised “pay to win” or “pay to play” aspects of traditionally material-driven sports like sailing where costly more advanced equipment creates a huge advantage for those who wield it.

We felt like a lot of riders wanted to see this in wingfoil – to enjoy the benefits that one design brings. That’s why we’re here, and that’s what this is: The X-15 Class – one-design wingfoil racing featuring the latest cutting-edge equipment.

May the best rider win.

EXCLUSIVE ULTRA X CANOPY NEW

An ultralight weight 3-layer laminate.
4 times more durable than a woven canopy.
Woven base layer enhanced with ultra-light PE mesh to carry primary load.
Fused together with a low stretch 0.25 mm film.

  • LOW STRETCH
  • ULTRA RESPONSIVE
  • LIGHTWEIGHT 86 GSM

HO’OKIPA ULTRA PE LEADING EDGE & STRUT

Unmatched durability, lightweight and responsiveness. Ho’okipa is a unique composite built with a reliable woven structure, supercharged through Ultra-PE fibres, which are 32x stronger than polyester at the same weight. This tensile strength allows a Ho’okipa leading edge & strut to be inflated to significantly higher pressures, creating a wing that is lighter and more responsive than anything else on the market.

  • HIGH-DENSITY ULTRA PE
  • SUPERCHARGED WEAVE
  • INCREASED STIFFNESS

DACRON AIRFRAME WITH GRADIENT LOAD LEADING EDGE

The Leading Edge is comprised of a two-stage, high-tenacity Dacron Construction. Center segments feature new HD 260 Dacron with outer sections utilising a 160g High Tenacity Dacron.

  • FIRM MOUNTING POINT
  • DIRECT & RESPONSIVE
  • GREAT DURABILITY

DOUBLE SURFACE TECH NEW

Also known as double / twin skin sail, is an innovative design in winging that improves airflow over and around the wing’s Leading Edge, greatly improving aerodynamic characteristics and remarkably increasing upwind angle of attack. The double surface design creates a low-drag, aerodynamic surface that eliminates the separation bubble behind the leading edge, significantly improving wind flow in this key area.

*Available on 5.5 / 6.0 / 6.5

REEF ZIPPER TECH NEW

The first wing to feature a reduceable canopy size, Reef Zipper Tech by FreeWing allows the wing to be easily and rapidly reduced by 1m2. This design feature allows a single wing to be used in greater wind range, eliminating the need for wing quivers and greatly reducing the cost of entering fair racing.

PRE-PREG CARBON BOOM NEW

The X-15 wing comes standard with our latest stiff and lightweight Pre-Preg Carbon Boom, delivering the ultimate in locked-in, responsive performance. Wrapped in grippy EVA, this one-size boom fits all X-15 wings for seamless compatibility.
The Carbon Boom is secured onto reinforced mount plates and handles harness line loads with ease, with dynamic load dispersion through large mount base pads.

RACE OPTIMISED 12.5° DIHEDRAL NEW

Leading Edge features a 12.5° dihedral providing a true vertical upper side of the wing when fully powered. This allows for a true 90° right angle to the plane which provides the most effective wind catch and thereby increases the wing’s effective surface area. In flight mode, the upper wingtip is critical and the most effective part of the wing as it is further away from the water surface, thus exposed to the more “free” and powerful wind.

LARGE CENTER STRUT CONNECTION

The tapered strut features a wide and strong connection at the base, creating a stiffer overall airframe.
Pumping becomes more efficient, improving acceleration and high-end power/ speed.

OPTIMISED LE TAPER RATIO

Optimised taper ratio to extend low-end ability. The wing is faster, more stable and maneuverable due to the Leading Edge.

DUAL INFLATIONS VALVES

To fine-tune wing performance, riders need to optimise pressures in the leading and center strut independently. For this, we’ve added a second inflataion valve to the centre strut to allow for precise pressure control.

OPTIMISED GEOMETRY

Medium-aspect wing ratio together with short strut for compact power balance makes the wing more maneuverable, performing better through tacks & gybes, and when flagged out.

DUAL VISION WINDOWS NEW

Racer safety is paramount. Double window design on each side of the wing achieves a high-degree field of view while maintaining minimal weight. Suitable for use in all climate conditions.

FreeWing-AIR-V3_Leash

SIZE-SPECIFIC WRIST LEASH INCLUDED

Strong, recoil leash matches the length of the strut when stretched, yet always have as short a leash as possible to prevent getting tangled.

ONEPACK WING BAG NEW

Go all-in with a single bag. The vented bag accommodates both the wing, pump and accessories, equipped with boom attachment points and carrying straps for your on-the-go lifestyle. Also features external and internal pockets.
*Pump not included”

FreeWing-Nozzle-Adapter

NOZZLE ADAPTER INCLUDED

Allows you to turn your inflatable SUP pump into a FreeWing pump.

Available Sizes

4.5 / 5.0

Designed with usability and accessibility as core, sizes 4.5 and 5.0 utilise single surface for ease of use with a strong Dacron airframe to create a great value wing. Designed for age groups U13 & U15 to get young riders into wingfoiling and progress.

5.5 / 6.0 / 6.5

Featuring double surface tech and Ho’okipa airframe, sizes 5.5, 6.0 & 6.0 are designed for maximum performance and durability. This wing has been specifically created for age groups U17 to Senior, where riders demand the most out of a wing.

for every FreeWing sold

FreeWing plants 1 mangrove tree with Worldview International Foundation. Each Mighty Mangrove sinks down 673kg of VCS-certified CO2 during its first 25 years.
Offsetting the wing’s Carbon Emissions more than 10 X over while also funding livelihood projects in Myanmar.

We also collect 1.1 kg of beach / ocean plastic trash – equivalentto the amount of plastic trash entering the ocean, per person,per year. Starboard balances this amount for our customers.
