Seafarer unions warn tired tugboat captains could crash in Panama Canal

Overworked tugboat captains could cause a major crash on the Panama Canal if work rules aren't changed, unions warned in a report issued Thursday.

The study found the 2016 widening of the canal to allow larger ships and a 2017 decision by the Panama Canal Authority (ACP) to remove the second captain from the tugs has kept the captains from getting the rest they need, raising the possibility of catastrophe.
