A Great Lakes bulkers was damaged in a grounding after its captain took on too many responsibilities at once.
The US National Transportation Safety Board (NTSB) said the accident involving the 36,200-dwt American Mariner (built 1980) happened on 7 January last year while it was outbound in the Vidal Shoals Channel, near Sault Ste Marie, Ontario, heading from Canada to Superior in Wisconsin.
