The GUNSAILS X-Over Fin is your go-to choice for variable conditions – whether you're riding choppy lakes or enjoying small waves on coastal spots. Inspired by the Power-Wave Fin, the shape has been completely reworked into a dedicated X-Over Freemove design – ideal for bump and jump sessions with plenty of sail pressure. 

The thin profile and stiff base section ensure early planing and top-end speed, while the more flexible tip in larger sizes gives you added control in tight gybes and snappy turns – exactly what you need in unpredictable, high-wind conditions. 

Your setup for windy action: Whether it’s gusty inland lakes or messy waves, the X-Over Fin gives you reliable grip, precision and control – whenever and wherever you push it. 

Key features

  • Thin profile & stiffness – for fast planing and high speeds 
  • Controlled flex in the tip – for precise gybes and quick turns 
  • Perfect for freewave boards & high-wind bump and jump 

Grab the GUNSAILS X-Over Fin and ride with confidence in any high-energy freeride session. 

Note: The fin size is given in millimetres and refers to the fin’s depth.
