It is shown experimentally that a necklace vortex is formed around a body moving on the water surface with velocities higher than 23.2cm/s. The necklace vortex is produced as the result of a hydraulic jump, and is governed by the velocity of body, shape of body and Froude number. The intensity of necklace vortex can be reduced by fitting a spike, beak or sphere to the nose of the body. The vortices due to the hydraulic jump are also produced at the shoulder and back of the body.
