 Basilisk displaced 1,360 long tons (1,380 t) at standard load and 1,790 long tons (1,820 t) at deep load. The ship had an overall length of 323 feet (98.5 m), a beam of 32 feet 3 inches (9.8 m) and a draught of 12 feet 3 inches (3.7 m). She was powered by Brown-Curtis geared steam turbines, driving two shafts, which developed a total of 34,000 shaft horsepower (25,000 kW) and gave a maximum speed of 35 knots (65 km / h; 40 mph). Steam for the turbines was provided by three Admiralty 3-drum boilers. Basilisk carried a maximum of 390 long tons (400 t) of fuel oil that gave her a range of 4,800 nautical miles (8,900 km; 5,500 mi) at 15 knots (28 km / h; 17 mph). The ship's complement was 134 officers and enlisted men, although it increased to 142 during wartime.
