Service history

Ordered in 1927, Rangitiki was launched in 1928 and entered service with the New Zealand Shipping Company in 1929 sailing between Great Britain and New Zealand on the route via the Panama Canal.[3]

At the start of the Second World War the ship was used for transporting children from Britain to Australia before being converted into a troopship. In November 1940 Rangitiki was the largest ship in Convoy HX 84 when the convoy was attacked by the German cruiser Admiral Scheer. Rangitiki and most other ships in the convoy escaped due to the actions of escort Captain Edward Fegen, commander of HMS Jervis Bay, who sacrificed himself and his ship to give the merchant ships the time to get away.[3] The following month the Rangitiki had another close shave when sailing as part of Convoy WS 5, the convoy was attacked by German cruiser Admiral Hipper.[3]

Returned to service between Britain, Australia and New Zealand in 1945 the Rangitiki carried numerous servicemen home from Britain as well a number of war brides. Following an extensive refit in 1947–48 the ship was then used by the New Zealand Shipping Company and continued in service until July 1962 when after 87 peacetime return voyages between Britain and New Zealand it was withdrawn. Sold for scrap, Rangitiki sailed to Spain and was broken up in Valencia in October 1962.[1]

Modifications in service

Both before and after its maiden voyage the ship was found to have stability issues especially when sailing in ballast so modifications including reducing the height of the ship by removing most of the bridge deck, shortening the funnels and adding more permanent ballast were made.[1]

During the refit in 1947–48 the John Brown built Sulzer type engines were replaced with two Doxford diesel engines with a total power output of 12,920 hp (9,630 kW) raising the ships maximum speed to 16 kn (30 km/h; 18 mph). At the same time passenger capacity was reduced to 405.[1]
