Description
THE ULTIMATE JUMP N' RIDE SAIL BEING AN IDEAL MATCH WITH FREEWAVE AND SMALL FREERIDE BOARDS
Bringing back the legendary DUKE was a daunting task that took over 1,5 years of intense development. At DUOTONE, you, the final user is always at the centre of our development. Therefore, especially with the new DUKE it wouldn’t have made sense to “just” rely on team rider input and feedback. As a starting point we involved “real” end-consumers who use these kinds of sails regularly and our surf centres to define a bucket list for the new DUKE.
Product code 14230-1204
Key Features
DRAFT FORWARD
Forward draft turns power off and goes completely neutral during manoeuvres >> results in a much higher success rate
BATTEN FREE CENTER
Larger gap between the foot batten and the batten above the boom >> better inflation (= planing power) in the boom area and improved stability in the upper sail area
LIGHT DONE RIGHT CONSTRUCTION
Weight reduction of a clearly noticeable 200 to 300 g without reducing the thickness of the main panel thus maintaining the well-known durability and longevity!
EPOXY BATTENS
Unbreakable Epoxy Battens
VTS TAIL OUTHAUL SPECS
Each sail carries individually defined visual indications for the correct outhaul extension (requires VTS TAIL boom).

ATTENTION: since the mast geometry and length (= stiffness) depend on the sail design, size and luff curve the sails will NOT work with any masts outside the recommendations!
I purchased two Duke's in 5.4/5.8 as part of a wholesale change of brand from Ezzy to Duotone. Great service and help from Sam and the Baker Boys and a great sail. Light in the hands and pulls well giving great control and effortless jumps. Helpful tuning guides make for easy rigging and tuning and the sail seems to have good wind range. Early days but really pleased with the change so far.
