JP Downwind S-Tec 2025

The true downwind SUP foil board !

Downwind foiling for paddle and/or wing.

This downwind SUP foil board provides exceptional stability, glide and paddle speed for easy, early take-offs. The sloped, concave deck shape helps convert paddling power into forward momentum. Its unique flat bottom section under the standing area ensures stability, while the rounded nose and sharply beveled tail deliver smooth touchdowns and efficient flight engagement. Built in our most advanced S-TEC technology, the board combines super low weight with the stiffness and quick response of this high-performance carbon construction. New tracks make foil assembly easier, and the mirrored foil positioning scale on the EVA pad ensures precise placement for enhanced control.

While many downwind-specific SUP shapes on the market share similar designs, we have decided to take a different approach for our Downwind S-TEC. We believe that the extreme beveled or fully rounded bottom and rail shapes create significant instability that causes discouragement for beginners. Therefore, we decided to go for a very flat bottom section where it matters the most: Right in the standing area. The stability to get going is the primary objective here. We have used the advantages of roundness and beveled rail/bottom contours only where they are needed. The nose area is rounded for forgiving and smooth touchdowns, while the abruptly beveled pin-tail can be easily sunk as you engage it to achieve flight. We paid special attention to the shape of the rail with keeping the apex of the rail radius as high as possible to further enhance stability. The deck features a slight concave in the standing area that transforms into a slope towards the nose, ensuring optimal engagement as you transfer the paddle power into the forward momentum. Simply put, the slope prevents the front foot from sliding forward in the crucial moment of the paddle stroke.
Apart from the importance of the shape features, the next essential characteristic of a good downwind board is keeping it as light and stiff as possible. Low swing weight and stiffness for a direct response are essential. Here we decided not to cut any corners. We offer the board exclusively in our most advanced high-end S-TEC technology. Precise CNC cut core is wrapped in a full PVC sandwich with lightweight Biax carbon and additional UNI-directional Carbon patch covering the length of the standing area as well as the mirrored bottom area supporting the foil. A special method of lamination is used to achieve a pre-preg resin-to-fiber ratio. This creates a feather weight Triax carbon PVC sandwich shell for the ultimate in composite board construction.
To further enhance the weight saving, we opted for a brushed-off topcoat covering the carbon. The faded painted nose and tail rail area with bright and fluorescent colors are there for visibility and safety at sea.

ALL-NEW TRACKS!
We redesigned the tracks that now have large openings for an easy foil-to-board assembly: Simply drop the plate nuts into the track while they are mounted on the foil, slide them into position and tighten the screws. To remove the foil, just loosen the screws and slide the foil backward and upwards.
We decided not to add any additional openings to the tracks as this would dramatically reduce their structural integrity. All boards featuring the new tracks are now equipped with a standard set of 4 plate nuts. These nuts ensure a perfect fit to the tracks, superior load distribution and ideal thread engagement.
The foil positioning scale between the tracks is mirrored in the design of the deck EVA pad, allowing you to know exactly where your foil is placed in relation to your back foot position.
The EVA pad has a fine corduroy pattern for comfort.
