Abstract
A speed indicating device or gauge is mounted on the forward flat upper surface of the water ski. This indicator is so mounted that the user of the ski during water skiing may view this speed indicating device. The indication is achieved by a pitot tube-like device in which one end of the tube is connected to the meter and the other end is disposed on the ski underside and at the rear thereof. The tube is filled with liquid to a point near the rear of the tube where a flexible diaphragm seals the tube. The diaphragm is actuated by the pressure of the fluid flow created by the rate of travel of the ski in the water.
