The Traveling Camera Apparatus for Surfing is embodied to film and photograph a surfer in motion on a breaking wave. The Traveling Camera Apparatus for Surfing is intended to have a full range of motion with functionality in 6 degrees of freedom and with the ability to operate in and out of the water. The advent for such an apparatus is motivated by the advance of the surfing photography/videography industry. The economic feasibility of the invention is spawned by the advent of wavepools equipped with breaking wave making devices that impart to creating breaking waves for surfing in a controlled environment. In such a wavepool a surfer may travel an entire length of the wavepool as permitted by the propagation of the breaking wave. The Traveling Camera Apparatus for Surfing shall be designed to follow along side the subject and create a multitude of images not possible if the camera were stationary in the wavepool. Some popular and sought after vantage points in the surfing photography industry are obtained when the camera is located directly behind the surfer submerged in the breaking wave and directly adjacent to the surfer where the camera is actually submerged in the water body of the breaking wave. In order to film the motion the surfer over the entire duration of the breaking wave, these camera angles require that the camera actually travel a path across the pool similar to that of the surfer on the breaking wave.
