DeepFlight Merlin is a personal submarine by Hawkes Ocean Technologies, part of the DeepFlight line of submersibles. The positively buoyant[1] submersible was designed by Graham Hawkes.[2] The Merlin was the first winged open-cockpit submarine (a wet sub) available on the market,[2][3] and first three-man submarine in the "aero submarine" class,[4] representing a major advance in scuba diving technology.[5]

It travels up to 5 knots,[2] has an operating time of one hour,[2] and an open cockpit,[2] requiring the use of scuba gear by occupants,[2] and giving them 360-degree views of the space around them.[1] The sub carries three, two passengers and one pilot.[6] The occupants have "windshields" to protect them from the water stream.[7] It is capable of hydrobatic maneuvers[clarification needed] and 360-degree turns.[8] It weighs 750 kg, is 4.6 m long, 3.0 m wide, 1.2 m tall, and runs off battery power.[9] It is available as either a single-seater or two-seater.[9] The design work on the sub started in July 2009.[10]
