The HSC High Speed Jet is a 74 m (243 ft) ocean-going catamaran built in 1990 by Incat for Hoverspeed and currently owned by Seajets. In 1990, as Hoverspeed Great Britain, she took the Hales Trophy for the fastest eastbound transatlantic journey, making the run, without passengers, in three days, seven hours and fifty-four minutes, averaging 36.6 knots (67.8 km/h; 42.1 mph).^[2]

The ship's previous names were: Hoverspeed Great Britain (1990–2004), Emeraude GB (2004–2005), and Speedrunner 1 (2005–2008, when she sailed the Mediterranean Sea for Sea Containers and Aegean Speed Lines.^[3]) Sea Runner (2008–2011) and Cosmos Jet (2011–2015, when she first began operating for Seajets).

She entered service on the Portsmouth to Cherbourg route on 12 July 1990 operating three round trips per day.^[5] HSC Hoverspeed Great Britain was replaced on the cross-channel route by MDV 1200 class ferries Superseacat One and Superseacat Two.

Power is supplied by four Ruston 16RK270 V-16 marine diesel engines each with a 3600 kW (4825 hp) at 100% maximum continuous rating (MCR).

The 16RK270 engine has 16 cylinders, a 270 mm bore and a 305mm stroke, for a per cylinder displacement of 17.46L and a total displacement of 279.408L. The vessel in trials attained over 48 knots (89 km/h; 55 mph) on a 5-minute run; at full displacement she showed 45.20 knots (83.71 km/h; 52.02 mph) maximum and 44.08 knots (81.64 km/h; 50.73 mph) for a two-way average.
