Abstract : The patent relates to a portable salvage lift apparatus for use in an underwater environment comprising a buoyancy system having a variable lift capability and a tethering system employing a brake comprising a pump. This pump has a rotor coupled to a reel in the tethering system, an inlet to admit water to the pump and a restricted outlet to increase the resistance to water flow through the pump thus resisting rapid rotation of the reel, whereby the rate of ascent of the apparatus is controlled.
