Developed in Margaret River, Australia, by our congenial design duo Patrik Diethelm and Fabio Canella, this sail has met our riders highest expectations right from the start. The 4Wave offers a fairly unique concept of innovative backhand-powercontrol. By defining the profile of the sail with a special mix of materials - from a soft dacron in the front to the stiffest x-ply in the back of the sail - we could reduce the twist of the sail body above the boom in a positive way that offers you that little bit of extra horsepower – constantly available whenever you need it. Key to the 4Wave's outstanding efficiency is the wide outline in the centre of the sail while keeping a standard boom length. The panel above the boom gets the cleanest airflow so the wide panel can create drive and power while the narrow top guarantees for easy clew-first behaviour. This sail's mighty low-end acceleration can easily outperform bigger sails, so for the full experience make sure to ride your 4Wave smaller than you usually would: With on pull of the backhand you can always unleash the power while you benefit from faster rotations, more radical turns and last but not least a better wipeout-resistance of a smaller sail in big surf.
