Some time ago, developer Finn Noer solved one of the biggest problems for many hobby surfers with his NoerStick by inventing an extension that adjusts its own length when trimming. The problem of the extension either being set too short or protruding too far at the bottom is now history.

The first step is to hook in the luff tensioner and tighten it by hand so that the trim block of the sail ends directly at the bottom of the trim block of the extension. In the second step, the adjustment ring of the extension is pulled up via a pull mechanism until the desired luff tension is achieved.
