Every now and then, a groundbreaking invention emerges and leaves a lasting impact on the sport. More than 20 years ago, it was the quick release boom; today, it's the POWER.XT. Both represented a revolution in windsurfing. POWER.XT is the first and only mast extension with an integrated lever that can handle any downhaul force while allowing for precise tuning, even on the water! As a result, even kids can completely handle the luff tension of modern slalom sails and accurately adjust any profile within seconds.
PINLOCK.XT
The classic extension for traditionalists, identical with POWER.XT, yet without its lever mechanism. The same friction-free and easy-to-use pulley arrangement facilitates trimming and reduces the time needed to get on the water.

POWER XTR

The race and luxury version of POWER.XT. The lever is 3cm longer, increasing the power ratio to approx. 1:60. The new 6-screw cleat plate and the tougher material of the extension tube can easily withstand the downhaul tension of very large sails, which can be fully trimmed with just one hand. Moreover, the indestructible Dyneema rope helps reduce friction.

NEW: POWER.XTi
Uncompromising high-end Race extension with a lever ratio of 1:80 and a longer lever, which for the first time will also smoothly work with twisted roller blocks (attention: no loop-loop-go!). For this purpose, two thin rollers are located on the outer side, allowing the rope to move without friction. This means that even huge Race sails with enormous trimming forces can be used, since all three rollers on the sail block can be used. Of course, the new POWER.XTi also features a finest-quality, indestructible Dyneema rope.
