Inspired By A Legend

The X-15 Foilboard takes inspiration from our renowned X-15 Windfoil Slalom range and incorporates elements from our best-selling foilboards. This high performamce race foilboard is crafted to deliver exceptional early planning capabilities and high-speed performance with low lift foils.         

        

X-15 Class | 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.

Wide Wind Range

Specifically built to cater a large range of winds, the X-15 is the board of choice in any wind range. We have presented only one size as we believe this is the best size for racers intermediate to advanced, in almost every wind condition.         

Get On Foil Earlier

The side cutaways concept has been pushed to the max to develop extra speed in displacement mode to get on foil early; you can take off even before reaching planing speeds.

Use Even Smaller Foils

The increased volumed combined with a highly effiecient hull design means riders can use smaller front wings and still get flying, which means even higher top end speeds.

Deep Tail Cutaways

The cutaways have been extended to decrease drag before take-off and accelerate the transition into flight mode by quickly reducing wetted surface area as speed increases.

Class Leading Aerodynamics

The board is shaped like a waterdrop from the nose to the tail, reducing drag and increasing aerodynamic efficiency. Reduces drag by up 60% compared to conventional boards, resulting in increased speed and improved stability during flight.

Fast, Controlled Touchdowns

The X-15 is designed with a large hull Vee built into the nose rocker. This shape has been designed and tested for extreme conditions, able to touch down at full speed and re-launch without losing speed or control.

Deck’s Rounded Profile

The X-15 features a slight convex deckshape for the highest efficiency. Airflow over the board is stable and has minimum resistance, maximising speed potential, stability and precise handling.

Extended Tail Area

Provides additional balance before takeoff and minimizes drag while in the air.

Precision Flight Control

A slightly recessed standing area gives the rider the most precise positioning and connection to the foil. Built to be aerodynamically efficient while accommodating for the most natural feel at high speeds.

Race Tuned Footstrap Inserts

Inserts for foot strap placements are tuned for maximum control during high speed racing and feature a range of insert options for different wind speeds and foil configurations.

Lightweight Footstraps Included

The Drake Ultralight MK4 footstraps are ideal for high performance foiling. The Ultralight MK4 straps featurea elongated screw slots to allow racers to set their back strap extra-wide using hole spacings further apart. This allows the rider’s foot to shift forward for downwind and backwards for upwind. Perfect trim adjustment on the fly.

Deep Tuttle Box

For the best possible connection to the foil, the tuttle box brings your foil millimeters to your foot for the best control at high speeds.

Board Sock Included

Reduces paper waste while protecting your board from dust, scratches, and UV damage. Made with stretchable polyester, it fits various board shapes. Ensure optimal board maintenance with the iconic blue Board Sock, featuring a secure drawstring closure.

6’0” x 21″ / 82L

Rider Weight: 35 - 80 kg

The 82L X-15 is our performance wing racing concept, built for speed and designed to accommodate a range of racers. With a blend of streamline aerodynamics, and 82L of volume, the X-15 is made to compete in various races and in all wind ranges. This model features a slightly lowered standing area for excellent control.
X-15 Class: U19 and below age groups use 82L Lite Tech, while the 82L Blue Carbon Sandwich is reserved for Open Women’s division.

6’0″ x 22″ / 95L

Rider Weight: 70 - 100 kg

The 95L X-15 is a high-performance racing machine, designed for speed, features an aerodynamic design for efficient and stable flight. The increased volume (up from 82L) ensures earlier and easier take off for heavier riders, and is the designated model for the Men’s category of the X-15 Class. This board excels in various racing conditions and wind ranges. The slightly lowered standing area provides exceptional control and stability, allowing riders to push their limits.

Blue Carbon Sandwich Foilboard

STRONGEST AND LIGHTEST

SENIOR WOMEN & MEN

The X-15 is designed with the highest performing construction, Blue Carbon Sandwich. Featuring a full PVC carbon sandwich layup for the lightest and strongest construction.

This performance-oriented Wingfoil Racing board combines cutting-edge design elements and high-performance features to offer an unparalleled racing experience. This board is built to push the limits and deliver exceptional speed on the water.

Lite Tech Foilboard

LIGHT, STRONG, AFFORDABLE

U13 / 15 / 17 / 19

Introduced as a more value-oriented board, this construction makes wing racing for the U19 age groups and below in the X-15 Class more accessible than ever.

Extra rigidity with the introduction of unidirectional stringer bands and solid with added rail/ nose reinforcements.Australian pine on the standing area for extra impact resistance and rigidity in the most critical area.All inserts have added high-density foam reinforcements.
