Control Wave Fin US + Slot Box
GUNSAILS Control Wave Fin – Precision and control for endless wave rides
Take your wave sessions to the next level with the GUNSAILS Control Wave Fin – a high-performance G10 wave fin designed for windsurfers who want full control and power in every turn. Whether in side- or onshore conditions, this fin delivers precise down-the-line performance and dynamic, flowing maneuvers.
The slim profile ensures fast planing, while the pronounced rake and flexible tip give you a smooth yet reactive ride. The tuned flex provides strong drive in bottom turns, and the high-quality G10 construction snaps back instantly for explosive cutbacks.
Built for demanding wave riders who need reliability, precision, and performance on every session.
Key features:
- Fast planing due to thin profile
- Maximum control with strong rake and flex tip
- Snappy cutbacks thanks to responsive G10 rebound
- Durable and powerful – made for serious wave conditions
- Experience the perfect balance of speed, grip and flow – with the GUNSAILS Control Wave Fin.
Note: The fin size is given in millimetres and refers to the fin’s depth.
Compatible with US-Box and Slot-Box
Our fins with US/Slot-Box system come with a separate screw and pin, allowing for flexible use in both box types.
US-Box: Insert the pin into the designated hole and secure the fin using the screw.
Slot-Box: Neither pin nor screw are needed – simply leave them out.
This makes the fin compatible with both systems – perfect for maximum flexibility.
