Abstract

The car has one or more movable blades, which either transmit the effort to the water or glide freely through it without doing so. The blades (5) can pivot either at right angles to the rest of the car or on its lengthwise axis (2). Thus on the rowing stroke the blade bears against the car, and on the return one cuts through the water, so that the car need not be lifted clear of the latter.
