Question: What is The most dangerous hour in shipping?
Answer: 22:24 to 23:45
The C/M stands the 04-08 so he’s up and ready for the day workers to start work at 0800 and the Third Mate is given the 08-12 because the Captain is usually awake from 0600 to 2200 and is available to help the most junior watch officer.
But… from the time the Captain goes to bed till the Second Mate arrives for watch (at around 23:30) the Third Mate is the only deck officer that is awake. Not a problem if the Third has experiance but when green mates meet in restricted waters two ships passing in the night is anything but poetic.
