Duotone F_Pace 2025 black/blue

F_Pace is a versatile freeride/freestyle foil sail. Agile and easy to use. 4-battens in Style models and 5-battens in Ride models. Accessible foiling performance. Works with RDM masts.
 
Foilsailing is more popular than ever and is developing rapidly. Meanwhile, in addition to classic foilriding, foilstyling as a playful variation with a clear leaning towards freestyle is causing a lot of excitement and unlimited possibilities.

Both “playgrounds” have specific requirements that regular fin sails cannot meet. This is exactly why the completely redesigned F_Pace range consists of two differently designed models, which up to size 5.8 are clearly described as F_Pace Style while 6.4 and 7.4 come as F_Pace Ride. But both designs have one thing in common: they are spiked with innumerable, foil-specific design features that have a decisive influence on performance and result in extraordinary characteristics in their respective spectrum.

Only 4 (Style) or 5 (Ride) battens, a super short boom and a reduced luff curve combine to produce a favourably soft and very light foil sail. The high aspect outline with reduced top surface corresponds perfectly with the low water resistance of the hydrofoil and the hardly existing lateral forces. With less movement in the top, the rig remains stable over the board, for maximum control yet very reactive. The foot perfectly closes with the deck and allows for extreme angles against the wind, especially on the F_Pace Ride with the extended foot batten – yet thanks to the extremely concave outline without any negative influence to the handling!

Product highlights

Ideal for foil riding/styling
Straighter luff curve, short boom and a 4 or 5 batten-layout all result in a soft and super light sail ideal for Foil-Riding/Styling

Exponential foot concave
Extended foot batten avoids the sail becoming twitchy/unstable when flying while the exponential foot concave avoids a negative influence on the handling

X-Ply corners
Crashes while foiling can be tough - therefore we use XPly for all exposed parts of the sail (foot, clew, top)

Reduce Top Roach
Reduced head area increases stability and control as it reduces the movement of the upper sail to correspond to the lower drag of the foil

Reduce Loose Leech
To correspond to the lower drag of the foil

Sleeve inducer
Best of both worlds: Same rigging speed and rotation like a no-cam sail. -Same optimized air-flow like a camber inducer



 

Features

3D Top Cap

Optimised pull. On regular top caps and pin systems the webbing is connected in a “one-dimensional” way with the sail body (either side to side or front to back), which transfers the downhaul tension only in certain points. 3D TOP CAP allows a “three-dimensional” and very widespread transition of the downhaul forces into the sail body. This eliminates top fluttering and ensures a progressive loose leech extending the wind range. The integrated abrasion ribs eliminate the need for heavy, bulky reinforcements at the end of the luff sleeve

Polyester webbing only

Eliminating stretch and loss of tension. If it’s good enough for safety harnesses, it’s good enough for windsurfers! Duotone is the only manufacturer to use only polyester webbing for the (vario) top and the tack roller. This advantage of this compared to conventional polypropylene is the negligible amount of stretch. As a result even brand new sails will retain full luff tension and will not need subsequent trimming

---

TT TOP

Improved sail control at higher winds. Designer Kai Hopf originally designed the TT TOP for the WARP. The reduced, concave shape improves tension conditions for a more effective, three-dimensional top twist. This means the top twists not only horizontally, but also vertically under strong winds. By completely neutralising gusts of wind, the rig is kept steady in the rider’s hands, and thus works in a much larger range of winds

Irocket 2.0

iROCKET 2.0 batten tensioners are super-lightweight, aerodynamic and highly stable, consisting of high-quality components such as a self-lubricating, salt-water-resistant brass nut with stainless-steel screw which can withstand all batten tensions. Factory calibrated individual batten tensions using a torque wrench

---

HTS 2.0 Harnessline Trim System

Never position your harness lines incorrectly again. Do away with the tedium of adjusting to the optimum rope position, as well as the numb forearms and the endless fiddling around. Patented print on the sail shows exactly where the centre of the harness line has to be

---

X-Ply Plus

Because the factors of puncture resistance, durability and stretch evidently depend only on the thickness of the film used, Duotone uses only 150 or 100 micron thick films for their exclusive X-Ply Plus. In an extensive series of tests, designers have developed the ideal combination of necessary film thickness and number of threads

---

Mini Batten

These prevent unwanted leech flutter. Short and highly effective mini-battens which provide support for the areas between the battens and prevent undesirable flutter

---

Double Seam Technology

Double the durability with half as much stretch. Duotone manufactures products of unmatched quality which gives their sails a significantly longer lifetime. A key feature which helps to achieve this is the triple-stitch zig-zag seams. Unlike other products with their single-seam design, these are double-seam. They cover all exposed crash areas, which increases tear resistance and reduces bending-elongation by up to 50%, boosting profile stability and performance

---

Mast Sleeve Opener

Frictionless insertion of the mast into the luff sleeve. An ingenious solution does away with the tedium of inserting the mast. Duotone logo above the boom cutout gently opens the sleeve so that the mast can be threaded with one hand into the luff friction-free, without having to constantly make adjustments to the luff

---

Individual boom length indication

Correct boom length without the need for trial and error. Because the boom is attached to the mast at different heights depending on body size, and because this creates a different angle to the mast, the boom length will vary. Specific recommendations for the correct length are printed directly on the luff sleeve at the boom level

---

Twin Strap

This keeps the sail rolled up and holds the protector to the mast. A brilliantly simple fastening system which keeps the sail compact and closed after being rolled up and, when on the water, holds the mast protector closely to the mast

---

Triple Tack Roller 3.0

Find the perfect trim with minimal effort. The integrated, nickel-plated brass triple roller minimises the downhaul forces tremendously
