In the meantime, Alex Cornelissen was captaining the Farley, and he decided to take the ship out to sea for a couple of days to patrol for illegal long-lining within the reserve.
The same U.S. ship -- with the help of an HC-144 maritime patrol aircraft -- spotted and intercepted a similar boat with six migrants south of Marathon, Florida.
The ship drifted undetected until late last month when a Canadian coastal air patrol spotted it several hundred miles off the Queen Charlotte Islands, an archipelago on the north coast of British Columbia.
