Sea Witch was a MARAD Type C5-S-73b container ship built at the Bath Iron Works shipyard for American Export-Isbrandtsen Lines. She operated in the Atlantic trades for five years. So engaged on the evening of June 1, 1973, the vessel was involved in a disastrous collision with the oil tanker Esso Brussels in lower New York Harbor and was damaged so badly that she was removed from active service.
