Thirteen Castle-class naval trawlers were commissioned. Apart from James Cosgrove and Wakakura, all were built in New Zealand by government directive, circa 1942. They were 135 feet (41.1 m) long, displaced 540 tons standard or 612 tons loaded, and were designed for a complement of 27. The three-cylinder engine of 480 indicated horsepower (358 kW) from A & G Price of Thames gave a speed of 10 knots (19 km/h). The coal-fired boiler was of the Scotch marine type. The boiler size governed the size of ship that could be manufactured, and as boiler plate of the required size was not available, two completed boilers and some partly completed boilers were supplied from Britain.
