3 in 1 Design

For an unprecedented trim range and an extremely wide wind range

Hyper Cam 2.0

Completely new and technically superior: the camber revolution with adjustable length - for optimised rotation and increased performance

Aero Sleeve Design 2.0

Maximum performance combined with fast waterstarting

Ibumper 2.0

The most advanced and effective molded mast protector

Irocket 2.0

Factory calibrated individual batten tensions using a torque wrench

VTS tail outhaul specs

Each sail carries individually defined visual indications for the correct outhaul extension (requires VTS TAIL boom)

Hyper CAM 2.0

Optimum performance and camber rotation at any time! HYPER CAM 2.0 is the camber revolution for even more sail performance. The secret is a variable slider which gets adjusted via a Torx stainless steel screw, determing the camber length (patent pending). Further extended results in maximum propulsion, slightly shortened optimizes the rotation. The difference is clearly noticeable and has a great influence on the performance level of the sail. The camber length can be changed by anyone within seconds and adjusted to his preferences, even under full sail tension. Despite this unique additional function, the HYPER CAM 2.0 is only slightly heavier since the housing is weight-optimized.

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

Foil eyelet

On all foil approved sails the additional lower clew eyelet helps you to position the sail further upright which makes the sail much more efficient when flying on the hydrofoil

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
