The SS "Arrow" was an oil tanker built by Bethlehem Steel Company, Sparrows Point, Baltimore, Maryland in 1948 as the tanker "Olympic Games". Renamed "Sea Robin" in 1960 and finally "Arrow" in 1962, the ship was a Liberian-registered tanker owned by the Sun Navigation Company. At 551.2 feet (167.9 metres) in length and 68.3 feet (20.7 metres) in width, with a draft of 29.9 feet (9.1 metres), she was an enlarged version of the standard American World War II tanker design and one of the oldest tankers in the fleet of Aristotle Onassis. The "Arrow" ran aground and spilled its load of oil into Chedabucto Bay on February 4, 1970. This remains the most significant oil spill off Canada’s East Coast, with some 10,000 tonnes (about 25% of the amount spilled by the Exxon Valdez in Alaska in 1989). Only the MV Kurdistan accident has come close, spilling about 6,000 tons of oil after breaking apart in the Cabot Strait on March 15, 1979.
