Renamed Sea Robin in 1960 and finally Arrow in 1962, the ship was a Liberian-registered tanker owned by the Sun Navigation Company.
On February 4, 1970 in Chedabucto Bay, off the east coast of Nova Scotia and only 14.6 nautical miles from her destination, she ran hard aground on Cerberus Rock, a well-charted hazard to navigation.
The accident occurred mid-morning, halfway between high and low tide, as the tanker was driven by 60-knot southwesterly winds and blinded by a heavy mist.
The subsequent inquiry revealed that Arrow's depth sounder had not been operational for two months, her autogyro compass showed a permanent error of three degrees west and her radar had failed about an hour before she ran aground.
Fisherman were catching lobsters and fish completely coated in bunker C.[4] The Fisheries Research Board of Canada performed a series of experiments in May 1970 to evaluate aquatic life in the bay.
In preparation for the Curb, Royal Canadian Navy divers performed tests with equipment that would be used to penetrate the tanks on the Arrow and attach hose fittings.
Because of limited capacity on the Irving Whale and intermittent foul-weather conditions, the whole operation was completed in three phases totaling over 22 days.
On August 28, 2015, a Transport Canada aircraft spotted an oil leak in the vicinity of the wreck, and closer inspection revealed a crack in one of Arrow's decks.
