    • A removable sail for a paddle-style boat, such as a kayak preferably takes the form of a fast deploying down-wind sail attachable to a deck of the kayak. The sail includes a curved, but non-circular shaped flexible material coupled to a collapsible, continuous frame member, for example the frame member may be sewn into a channel made by the material. When mounted to the deck of the boat, the sail may be arranged in a deployed or a stowed configuration, the latter being deployable on the fly in that the sail can be quickly sprung into the deployable configuration. The non-circular shape of the sail cooperates with a hull shape of the boat while providing a sufficient surface area for capturing wind energy. The sail may also include a transparent region that helps prevent excessive amounts of spray from striking the paddler and yet still provides an adequate viewing range.
    • 用于桨式船(例如皮划艇)的可拆卸的帆优选地采用可附接到皮划艇甲板上的快速展开的下风帆的形式。 帆包括弯曲但非圆形的柔性材料,其联接到可收缩的连续的框架构件,例如框架构件可被缝合到由材料制成的通道中。 当安装到船的甲板上时,帆可以布置成展开或收起的构造,后者可以飞行地展开,因为帆可以快速地弹起到可展开的构型中。 帆的非圆形形状与船的船体形状配合,同时提供足够的用于捕获风能的表面积。 帆还可以包括透明区域,其有助于防止过多的喷雾撞击桨,并仍然提供足够的观察范围。
