The PW4 is our power wave sail designed for speed, and action in all conditions. Based off the KS3, we redesigned the shape of the sail above the boom and added an additional batten. The result is power and speed not found in any of our other wave sails.

For larger sailors this is a boost that levels the playing field with smaller sailors on less powerful sails like the KS3. The sail has a significantly tighter leech and even when rigged with high downhaul tension, the twist point of the sail is much higher up the leech delivering more power.

The PW4 includes the full-size Wave Vision window all the way to the sleeve for unparalleled visibility. The feel is stiffer and more direct than the KS3 or the QU4D. For jumping, the PW4 is a forward looper’s dream sail with instant whip when sheeted in. If you ever wanted to try a double, this is your sail!

35 years of sail making and service in the toughest wave sailing arena; Maui, has made the construction of the PW4 and all our wave sails second to none.
