Incremental fine-tuning over the entire range.
The Force 4 is our purist wave sail that is equally at home in all conditions—sideshore, onshore and offshore. It features high-tech, lightweight construction and a draft-forward shape that strikes a perfect balance between power and responsiveness and provides an “in-between-the-hands” feel that makes it exceptional for both wave riding and aerials/tricks. The Force 4 is our most versatile wavesail and also stands as an excellent choice for freestyle riders.
