Expedition windsurfing is using a specially designed vessel capable of carrying 3-4 days of supplies for multiday camping trips. It can be sailed as a windsurfer, paddled as a sit-on-top kayak or as a stand-up-paddleboard (SUP). Used for long expeditions, adventure racing, short trips along the coast, island hopping or exploring the back country inland water ways. It combines the adventures of backpacking and kayaking with the thrills of windsurfing.
