Abstract
A thrust device for manually advancing a water craft over a water surface includes a stick-like grip forming part of a stick carrying a thrust apparatus made of a flexible, substantially circular foil provided with radial stiffening members attached at equally spaced intervals along its circumference. A concentric stub-like tubular opening connects the foil to the stick near one end of the stick to be inserted in the water, and flexible tension members connecting the circumference of the foil to the one end of the stick define a maximum angle between the foil face and the stick when the one end of the stick is thrust into the water. Each tension member has one end attached to the edge of the circular foil and a second end. The second ends of all the tension members are led through a central hole in a cover slipped over the end of the stick and are joined into a junction larger than the hole in the cover.
