Robert Gaskin is a ship wreck in the St. Lawrence river outside of the town of Brockville, Ontario. The ship was being used to recover the wrecked train ferry William Armstrong. Lift pontoons were being lowered to help provide lift capacity to raise the Armstrong, but a chain connecting the Armstrong to a pontoon broke—as it came to the water's surface the pontoon struck the Gaskin . There was no loss of life when the Gaskin sank. There was an initial concern that the Gaskin struck the Armstrong and would have prevented the salvage of the Armstrong. The Gaskin, however, landed sufficiently far away that it did not damage the Armstrong.
