Our 4 batten wave sail offers the perfect balance of wave riding, flying manoeuvres and straight line performance to get you where you need to be, when you need to be there. The new Force 4 has been redesigned from the ground up with shorter luff lengths and a reduced luff area, and features a new ultra-light XS-1577 fabric. Developed in direct collaboration with Ricardo Campello, this sail offers more power than previous models, a lower centre of gravity and is lighter in the hand than ever before. The Force 4 is versatile enough to win in all conditions, making it the ultimate ride for anyone serious about surfing, regardless of ability.
