Abstract
An apparatus for timing of water-based activities or events, such as, sailboarding, yachting, motorboating and swimming. The apparatus comprises a rigid horizontal support bar, two vertical members attached to the ends of the support bar, buoyant floats attached to the vertical members and a transmitter/receiver package disposed on the vertical members. The apparatus acts as a gate which individuals or water-vehicles passing therethrough are detected or timed by the transmitter/receiver package contained thereon. The apparatus is kept stabilized by being secured to any nearby stationary object and by adapting the submerged portion of the apparatus to provide negative buoyancy.
