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.

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 2022 Wing Surfer MATADOR (5.0m Only)

, ,
Original price was: £789.00.Current price is: £349.00.

In stock

WING-SURFER MATADOR

SIZES: 3 | 4 | 5  The Wing-Surfer Matador is compact, light, and powerful. It is designed for wing foilers that want to use the smallest wing possible for the prevailing wind conditions, with a focus on riding swells and waves. The Matador has a deeper draft and larger diameter leading edge and strut than a comparably sized Wing-Surfer, with the power placed even further forward. The leading-edge taper is more pointed at the center and carries more dihedral across the wingspan. This all comes together to create a wing that drives upwind with ease, then flags in neutral with amazing stability and balance for riding waves, swells, and doing downwinders. With tons of sheet-in-and-go power, even heavier riders will find it easy to get up on their foil. Once flagged into neutral on a wave or swell, the light and nimble airframe all but disappears like a bull fighter’s cape — allowing you to carve and glide with ease. Thus, the name “Matador.” Unlike the all-around Wing-Surfer, the Matador is designed to be ridden mostly upwind then flagged downwind, so the windows are small and placed where an experienced rider needs them when riding windward, knowing that most of the time the wing will be flagged behind them with full visibility. PERFORMANCE FEATURES
  • Larger/stiffer diameter leading edge and strut for a rigid overall structure
  • Deep locked in draft for instant power
  • Optimized dihedral for luffing and flagging
  • Optimized handle positions
  • Removable and adjustable y-handles
  • Neoprene “knuckle guard” under center grab handles
  • Inflated Structure - no hard surfaces or hardware
  • Packs up small
  • Drawstring bag with pump storage feature
