I wonder if in the maritime world there is the equivalent of CRM (Cockpit Resource Management), as in aviation.
Too many lives were lost due to 1st officer never taking over command when the error in the commander's thinking had already become apparent or the entire aircraft was being flown, effectively, by a single infallible captain and not a team.
Lessons were learned decades ago and at least in a 1st world outfit I would like to believe that no 1st officer would hesitate to utter the words "I have control" when in such stress.
