In brief

What Union-Castle Line is

Full article ↗

The Union-Castle Line was a British shipping line that operated a fleet of passenger liners and cargo ships between Europe and Africa from 1900 to 1977. It was formed from the merger of the Union Line and Castle Shipping Line.
It merged with Bullard King and Clan Line in 1956 to form British & Commonwealth Shipping, and then with South African Marine Corporation (commonly referred to as Safmarine) in 1973 to create International Liner Services, but maintained its separate identity throughout. Its shipping operations ceased in 1977.

In context

How Union-Castle Line compares

Counts over companies and vessels actually held in this directory — not over the world fleet, which is larger. Nothing here is estimated.

With 5 vessels attributed to it here, Union-Castle Line is the 174th largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.

United Kingdom is the country of registration for 97 commercial operators in this directory, among which Union-Castle Line ranks 11th by ships on record. Between them those companies hold 260 vessels here. See every operator registered in United Kingdom.

Founded in 1853, Union-Castle Line is 173 years old. This directory holds 32 operators founded within five years either side of that date, whose median fleet on record is 1 ships. The median founding year across all commercial operators here is 1966, and the oldest on record dates to 1514.
