| (via Wikipedia) The Armidale class patrol boats are 56.8 metres (186 ft) long, with a beam of 9.5 metres (31 ft), a maximum draft of 2.25 metres (7.4 ft), and a displacement of 270 tons. The semi-displacement vee hull is fabricated from aluminium alloy, and each vessel is built to a combination of Det Norske Veritas standards for high-speed light craft and RAN requirements. The Armidales can travel at a maximum speed of 25 knots (46 km/h; 29 mph), and are drien by two propeller shafts, each connected to an MTU 16V M70 diesel. The ships have a range of 3,000 nautical miles (5,600 km; 3,500 mi) at 12 knots (22 km/h; 14 mph), allowing them to patrol the waters around the distant territories of Australia, and are designed for standard patrols of 21 days, with a maximum endurance of 42 days. |
