Abstract: A transparent and shark-repelling surfboard or flotation board made of transparent super microcellular polymer foam with transparent coating. The surfboard or the flotation board has a locater device for locating large aquatic animals, and an alarm device for alerting a rider of large aquatic animals, such as sharks, located by the locater device. The surfboard or the flotation board also comprises a repellent or deterrent signal generator that is configured for transmitting interference signals to disrupt the electro-sensory perception system of the aquatic animals.

Abstract: The present invention includes a transparent surfboard or wave-riding vehicle. The present invention also includes a transparent surfboard with an optional embedded locater for large aquatic animals and an alarm for the wave rider, specifically prepared to identify animals such as sharks, and an optional shark-resistant signal generator that transmits an interference signal to interrupt the electrical impulses used by aquatic animals for electrical sense. More specifically these aquatic animals are greater than three feet in length (such as a shark) and within approximately a one-hundred foot radius of the surfboard with regard to the sensory perception of a shark, thus diverting or distracting it from any one in the water in the vicinity of the device. The transparency of the surfboard or wave-riding vehicle is achieved by manufacturing the surfboard blank with transparent super microcellular polymer foams and coating the blank with a clear, transparent polymer.
