RMS Pendennis Castle was a Royal Mail Ship, passenger and cargo liner operated by the Union-Castle Line. The vessel served the Union-Castle Line from 1959–1976 on a regular route between the UK and South Africa for the Southampton to Las Palmas, Cape Town, Port Elizabeth, East London and Durban "Cape Mail" service. After her withdrawal from service and subsequent sale by the Union-Castle Line in 1976, she was re-named consecutively Ocean Queen, Sinbad, then Sinbad I, however she never returned to commercial service after her Union-Castle Line service and was sold for scrap in 1980.
Design and construction
In 1953 Sir George Christopher assumed leadership of Union-Castle. Early in 1955 the company ordered Pendennis Castle from Harland & Wolff to replace the ageing RMS Arundel Castle which then had over 30 years of service. The new ship's keel was laid on 8 November 1955. On 31 January 1956 the Union-Castle Mail Steam Ship Co.Ltd merged with Clan Line Steamers Ltd. to form British & Commonwealth Shipping Company. The merger resulted in Clan Line people taking the leading role in the new company's management and they immediately decided to improve and enlarge Pendennis Castle even though she was already under construction.[1]
