Apparatus for protecting users of surfboards, kayaks and other personal water activity apparatus against sharks and other water-borne predators is provided. A plurality of lights is provided on the bottom and side surfaces of the personal water activity apparatus. The lights are actuated to mask and distort the shadow, shape or outline of the user together with the personal water activity apparatus, in effect camouflaging the user and his or her personal water activity apparatus. The lights may be actuated either manually or automatically. Sensors are provided to detect the stage of ambient light in order to automatically actuate the light sources.
