Tug tows generate such immense forces that when something goes wrong it goes very wrong and often tragically.In the case of Western Tugger a deckhand suffered fatal injuries while trying to release a tow wire attached to a capsized barge in a report from TSB Canada.
This was the third time that Western Tugger had towed the barge Arctic Lift I. This time the welded steel barge was loaded with rebar and bundled wood and the voyage went without problems for the next six days.
On 10 May at 0400, the mate on watch verified visually that the barge was towing normally.Footnote 10 Shortly after that, heavy fog rolled in, and the mate was unable to see the barge again during the watch. The master arrived on the bridge at about 0545, but was unable to see the barge. The mate left the bridge shortly after the master took over the watch.
