The Paluma-class motor launch is a class of four hydrographic survey motor launches operated by the Royal Australian Navy (RAN). Built in Port Adelaide between 1988 and 1990, the four catamarans are primarily based at HMAS Cairns in Cairns, Queensland, and operate in pairs to survey the waters of northern Australia.
The Paluma-class vessels are based off the design of the Prince-class roll-on/roll-off ferry. They have a full load displacement of 320 tonnes, are 36.6 metres (120 ft) long overall and 36 metres (118 ft) long between perpendiculars, have a beam of 13.7 metres (45 ft), and a draught of 1.9 metres (6 ft 3 in). Propulsion machinery consists of two General Motors Detroit Diesel 12V-92T engines, which supply 1,290 brake horsepower (960 kW) to the two propeller shafts. Each vessel has a top speed of 12 knots (22 km/h; 14 mph), a maximum sustainable speed of 10 knots (19 km/h; 12 mph) for a range of 1,800 nautical miles (3,300 km; 2,100 mi), and an endurance of 14 days.
The sensor suite of a Paluma-class launch consists of a JRC JMA-3710-6 navigational radar, an ELAC LAZ 72 side-scan mapping sonar, and a Skipper 113 hull-mounted scanning sonar. The vessels are unarmed. The standard ship's company consists of three officers and eleven sailors, although another four personnel can be accommodated. The catamarans were originally painted white, but were repainted naval grey in 2002.
