PAN-ATLANTIC STEAMSHIP CORPORATION.

Pan-Atlantic’s flag is blue with a white diamond bearing black P-A, resembling Waterman’s design with different lettering. Brown 1958, US Navy and Mitchell show no funnel top; Jordan leaves the funnel-letter colour unspecified.

Waterman established Pan-Atlantic in 1933 for coastwise operations, leaving overseas routes to the parent. Malcolm McLean bought it in 1955 and subsequently acquired Waterman, converted the operation to container ships, and renamed it Sea-Land in 1960. Mitchell instead gives formation by McLean in 1956, renaming to Sea Land Industries in 1958 and sale in 1977. Rosanoski preserves these differences; the Historical Dictionary supports the 1960 renaming.

USA, Mobil; the same address as Waterman.
