Duotone Power.XT 2.0 SLS 2025

The Duotone Power.XT 2.0 SLS is the lightest ratchet extension ever made — and the only extension in windsurfing with a patented integrated ratchet system. Built for sailors who demand the best, the SLS combines a full T800-carbon tube with SENTEX® resin to shave weight without compromising the precision and reliability the Power.XT is famous for.

For years the benchmark in downhaul extensions, the Power.XT 2.0 SLS takes everything that made the original great and strips it back to the bare minimum weight. At just 530g, it is 180g lighter than the standard alloy version — a difference that is genuinely noticeable, even sitting as low down on the rig as it does. Sam, our owner, runs this on his wave sails and confirms it: you can feel it.

The integrated ratchet system — patented, and exclusive to Duotone — means you can downhaul any sail, from any brand, standing up, with almost no physical effort. The 15cm lever and 1:60 mechanical ratio overcomes even the strongest luff tensions, allowing millimetre-precise trimming in seconds. Whether you're rigging a wave sail on a windswept beach or fine-tuning a racing sail on the water as conditions change, the Power.XT SLS makes it effortless.

The simplified loop-and-go system means no complicated rope threading — pass the loop, lock it on the pulley, and ratchet up. The rapid release mechanism lets you de-rig just as quickly, with no kneeling on the floor. And thanks to the 2-thread system, it works with every sail brand on the market, not just Duotone.

Key Features

The Lightest Ratchet Extension Ever Made: At 530g in T800-carbon with SENTEX® resin, the SLS is the most lightweight ratchet extension of all time — and you really can feel it.
Patented Integrated Ratchet System: The only extension in the world with this technology. A solid, precise ratchet mechanism with a 15cm lever and 1:60 ratio — making extreme luff tension completely effortless.
Rig Standing Up: No more wet knees, no more sitting on cold sand or concrete. The Power.XT SLS lets you rig and de-rig entirely on your feet.
Re-trim On the Water: Wind picking up or dying mid-session? Adjust your downhaul tension while you're out sailing — no other extension makes this as practical.
Works With Every Sail Brand: The 2-thread system is universal. Wave, freestyle, freeride, or racing — whatever brand is in your quiver, the Power.XT handles it.
Rapid Release: Switch to minus, release one click at a time, and the sail de-rigs itself cleanly. No wrestling, no rope burns.
2-Year Unconditional Warranty: Register online and you're fully covered for two years — no small print, no conditions.

Tech Features

T800-Carbon + SENTEX® Resin Tube: The same ultra-high-modulus carbon construction used in top-end racing equipment. Exceptionally stiff, exceptionally light — 530g total weight.
LIROS® Dyneema Rope: Original high-strength Dyneema downhaul line — cut-resistant and built to handle repeated high-load tensioning without degrading.
iSNAP 2.0 Length Adjustment: The lightest and most intuitive length adjustment system available. Dial in your extension range with precision and no fuss.
Loop-and-Go System: Pass the loop through the eyelet, lock it on the pulley — that's it. No complicated rope runs, no knots to untie when de-rigging.
Always Leave in Plus: A key habit to protect the internal spring — always switch the lever back to plus after use and when storing. Leaving it in minus over time will wear the mechanism prematurely.
