We present the Patrik Foil S2 sail.
COMPETITION SLALOM/SPEED FOIL SAIL OPTIMIZED FOR FLYING ON THE LIMIT WITH MAX AVERAGE SPEEDS.
7-batten
4 cam
High-load X-ply panel
Extra large sleeve.
OVERVIEW
Control, control, control. The FoilS2 is a pure slalom and speed foil sail for the competition rider who is searching for the fastest and most technically advanced foil sail out there. The high aspect ratio design allows for perfect aerodynamics. We have optimized the sail for maximum average speed. The more controlled and equal the speed of your flight is, the easier you can move closer to the edge of what's possible in modern foil racing. You want the perfect foiling machine?! Here comes the PATRIK FoilS2.

CONSTRUCTION
Racing is a "no-compromise" area in Diethelm's dictionary. Every detail is optimized with maximum performance in mind.
All the panels inside the sleeve are made from the thickest monofilm available, which provides the best stiffness and a locked profile where the main shape is. The main panels are 5 MIL clear monofilm from B7 to B4 and then 4 MIL above that batten. Why always clear? Because this material is a few grams lighter than its colored alternative! For the foot panel and a minimalistic area around the clew, we kept a good impact resistance 5 MIL red x-ply materials. These are often stressed when your sail rubs on the deck grip of the ultra-wide racing boards. Along the leech, you will find 5 MIL (closer to the clew) and 4 MIL (closer to the top) clear x-ply to keep the rear edge of the sail stable and aerodynamically clean even in high-wind choppy conditions. For the mast sleeve, we reduced the amount of PE fabric material (which stretches more and absorbs small amounts of water) and maximized the 2 MIL x/scrim-ply area instead, which is super light but still has the highest number of fibers per sqm. This material is perfect for spreading the load across the entire sail.
TRIM
Be sure to set the required downhaul indicated by the color changes on the batten sleeves. Use the clew trim options to adjust the sail to the wind conditions.
PRO TIPS
"Fast and controlled, giving you the most stable flight without sudden load changes. This is the most advanced concept of a pure foil sail out there. Not lifting the nose in the gusts, never pushing you down and aerodynamically perfect!"
ALEX COUSIN (Sails R&D)
"For the DEFI competition, I need a sail with the best possible average speed, no matter how the conditions change on the long reach. The FoilS2 can handle difficult up- and downwind angles with ease and is the most controlled foil sai I've ever used."
NICO WAREMBOURG (2x DEFI winner)
"This is my favorite sail of all time. The Foil S2 gives me the control and speed I need to win races. Use the trim options to adjust the sail to your needs. Use the high clew position as standard and the low position to depower the sail and gain even more control."
MICHELE BECKER (German Tour Winner 2022)
