Starboard X-15 91 Carbon Reflex Sandwich 2023 Windfoil Race Board

The Starboard X-15 91 Carbon Reflex Sandwich 2023 is the 91 L size of Starboard's foil slalom board from the 2023 range. For 2023 Starboard launched 3 brand-new foil slalom shapes with extreme focus on aerodynamics and specific optimisation for small low-drag foil wings.

Technical sheet

2023 aerodynamic design

• Lower nose rocker: reduces aero lift and drag at high speed.
• Increased forward vee: prevents catapults during touchdowns.
• Soft convex deck: minimises drag.
• Very smooth tail exit: minimum drag at slalom speeds.
• Drop shape: tear-drop profile from nose to tail for top efficiency.

Carbon Reflex Sandwich construction

• Decks built with the lightest grade of biaxial and unidirectional carbon fibre.
• 45/30/0° fibre orientation optimises flex (absorbs chop) and reflex (returns energy).
• Premium full carbon: the competition lay-up.

91 L vs 95 L (2025 model)

• The 91 L is more agile — ideal for 65-85 kg riders who want reactivity.
• The 95 L (newer model) makes light-wind take-offs easier and accommodates riders up to ~100 kg.

How we recommend it at El Niño Mallorca

Only if you race or train race seriously. For recreational windfoil there are more versatile options (E-type, iQFoil). If you find a real discount and race X-15 Class, a very interesting buy.
