Bligh’s navigation skills were excellent while sailing that small boat after the mutiny and all his time as an officer. He updated Royal Navy charts as to locations and water hazards with his accurate surveys. The time ashore collecting the breadfruit out of ship’s discipline ruined his crew more than any lapse or act by Bligh. The Navy kept him on after the mutiny but he never got much in the way of promotions from then on.
Sorry but William Bligh achieved the rank of Vice-Admiral before he retired.
