1. A buoy provided with first and second fixed hydrodynamic surfaces, which when the buoy is towed through water by a tether, the first hydrodynamic surface generates a downward force that reduces with increased through-water speed, and the second hydrodynamic surface generates an upward force that increases with increased through-water speed, so that the buoy dives up to an upper critical through-water speed and rises beyond said upper critical through-water speed.
