Duotone Power.XT - Patented Ratchet Windsurfing Extension! Makes life much easier!

In Stock Now · Worthing Watersports

The only windsurfing extension in the world with a patented integrated ratchet system — and once you've used one, you'll understand why people say they'd quit windsurfing without it. The Duotone Power.XT 2.0 lets you rig any sail, from any brand, standing up, in seconds, with almost no physical effort.

No more sitting on wet ground. No more rope cuts from hauling bare-handed. No more being stuck with the wrong downhaul tension when the wind changes mid-session. The 15cm lever and 1:60 mechanical ratio means even kids can tension a large racing sail — and if conditions shift while you're out, you can re-trim on the water.

Key Features

Patented Integrated Ratchet System: The only extension in windsurfing to feature this technology. A solid, precise ratchet mechanism with a 15cm lever and 1:60 ratio that makes even extreme luff tension completely effortless.

Works With Every Sail Brand: The 2-thread system is universal — wave, freestyle, freeride, or racing, whatever brand is in your quiver. Duotone even fit a 3-pulley system on their sails so it works with any extension pairing.

Re-trim On the Water: Dial in your downhaul as the wind builds or drops while you're out sailing. No other extension makes this practical.

Rapid Release: Switch to minus, release one click at a time, and the sail de-rigs itself cleanly. No kneeling on the floor, no wrestling with rope.

LIROS® Dyneema Rope: Original high-strength Dyneema — cut-resistant, durable, and matched to the quality of the ratchet.

iSNAP 2.0 Length Adjustment: The lightest and most intuitive length adjustment system available. Millimetre precision, no fuss.

2-Year Unconditional Warranty: Register online and you're fully covered — no conditions.

Which Version?

Power.XT 2.0 — Standard Alloy (RDM 36): 7075+T8 sandwich alloy tube, 710g. Bombproof and dependable — a huge upgrade over any other extension on the market. Also available in SDM 28 and SDM 42, both upgradeable to SHOX.

Power.XT 2.0 SLS — Carbon (RDM 36): Full T800-carbon tube with SENTEX® resin. 530g — 180g lighter than the alloy version. Sam (our owner) uses this on his wave sails and can genuinely feel the weight difference, which is surprising given how low down the extension sits. If weight matters to your riding, this is the one.
