2025 Naish Force 4 Windsurfing Sail – Blue
Price 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.

Naish Force 4 Windsurfing Sail 5.3m – White Brand New (ONLY ONE IN THE UK)
This sail is the cut of an S26 but the material of an S25 Naish Fore 4 sail. The material used is Naish's X1-66, a material that was developed within the company over a number of years and noted for its durability and lightness. We believe this material was mistakenly used by the factory who produced the sail instead of the XS-1577 film (the sail cloth used on S26 and current Naish Force 4 sails). This sail will still performed superbly, it is brand new and has only been discounted due to being produced using the previous years material.
