The WindPaddle sail deploys in a matter of seconds. A continuous sheet (steering line) allows the paddler to easily control the sail while keeping the paddle in hand for steering. We also placed a large window in the center panel of the sail for visibility. The design puts the center of force of the sail down low, at about the same level as the paddler, making the boat/sail combination incredibly stable and easy to use. The Wind Harness (patent pending) allows you to quickly attach your WindPaddle onto any boat or switch between boats in a matter of seconds. If your boat has anything that can be clipped to - including thwarts, handholds on the gunwales, bench seats, deck lines, cleats or bungees - you can probably attach your WindPaddle to it! K3710 N3704
