X-15: It’s all about speed. Four all-new 2025 Carbon Reflex Foil Slalom shapes, covering minimum to extreme conditions: The 2025 X-15 evolution sizes 75, 79, 85 & 89 push the boundaries of aerodynamic improvement. Specifically optimized for use with tiny low drag high speed foils, while enhancing early takeoff practicality. Thinner overall profiles reduce aero drag, and minimize side wind interference. Flatter deck profiles reduce roll, while refined rear strap stance improves high wind control, yet retains light wind efficiency. Maximize your speed potential. Pure performance. Refined. And Redefined. The Starboard original waterdrop cut-away accelerates the water along the tuck line and gets you to take off speed with minimal delay. With the refined tail profile and enhanced underwater profile, getting smaller highspeed foils started is easier. Get up and fly. 2025 models gain even more stability through optimized aerodynamic airflow, with less aero drag than previous models. Taking it further, we package the whole design in lighter-weight Carbon Reflex technology without compromising strength.. The side profile of the new design is around 10mm thinner, and the rails are much thinner, which reduces aerodynamic drag, and further minimizes the negative effect of side winds interfering with board trim at high speed on the foil. As a result, the 2025 board is even more slippery and stable through the air than the previous benchmarks. Increasing the bottom wetted surface length by 15cm over previous boosts early subplaning speed and transition onto the foil. This makes takeoffs with smaller highspeed foil wings significantly more efficient, faster and easier.
