2025 Naish Force 4 Windsurfing Sail – Blue
£499.00 – £599.00Price range: £499.00 through £599.00
THE ULTIMATE 4 BATTEN WAVE SAIL
Through the past year we have worked with Ricardo Campello, Robby Naish and our test team to fine tune the Force 4. In addition to a fresh new color combo we went through and improved the range size-by-size.
For the 5.0 and up we kept the more powerful feel with a slightly tighter leech, accommodating the need for plenty of sail power, especially in onshore and side-onshore conditions. In addition to Maui, testing was done in Brazil and Italy, which helped to adjust those sizes for real-world conditions and make them extremely crisp and responsive.
Our sizes 4.7 and smaller received some slight adjustments to make the head open a touch more, making them feel even lighter in the rider’s hands while keeping the power necessary to perform in any conditions from side-offshore to onshore.
No matter which size you choose, the Force 4 is the perfect partner for anybody looking for a well-balanced 4 batten wave sail that carries its power neutrally between your hands and can handle the roughest conditions on the water.

WING-SURFER MK4
SIZES: 2.5 | 3.0 | 3.5 | 4.0 | 4.5 | 5.0 | 5.5 | 6.0 | 6.5 | 7.5 Designed to “check all of the boxes” in terms of performance, features, and range, the future of winging is here with the Wing-Surfer MK4. This fourth-generation Wing-Surfer combines the perfect balance of low-end power, rigidity, and twist for optimum sheet-in-and-go power and speed. An increased diameter leading edge and strut adds to the MK4’s stiffness, resulting in great stability and power. The Wing-Surfer MK4 has three long and ergonomic control handles for added comfort and control as well as an added ‘power handle’ for sheeting in hard and jumping. Smaller windows have reduced the Wing-Surfer’s overall weight with zero compromises in visibility. For those who are in search of the best combo of get-up-and-go power, a wide wind range, insane top speed, and unmatched jumping ability, the Wing-Surfer MK4 is the wing you can’t live without.Naish Airmax2 Pump for Wing & Kite to 12psi
