ABSTRACT:
A skate sail, to be held by hand, for propelling an individual on a mobile supportive device, such as skates or a skate board, has a central vertical brace, and a horizontal cross brace whose center is attached to the upper portion of the central vertical brace. Identical spars extend from the base of the central vertical brace past the ends of the horizontal cross brace to which they are secured. The edges of the cloth of the skate sail are secured to, and held tightly by the identical spars. The central, vertical brace may be secured to the central axis of the sail, and the ends of the horizontal cross brace can push the spars apart to keep the sail taut. The individual holds the rig at the intersection of the vertical and horizontal braces, which should be near the center of effort of the sail, in a suitable direction to cause any available wind to propel him on his skates or skate board in any of the possible desired direction.
