If peace time has 5-6 hours of sleep on a good day as the bar, what are they going to do if an actual war breaks out? It sounds like there is no margin left for them to use and it would only take a few casualties to make the boat unable to operate
They're probably already damaged badly enough from the lack of sleep in peacetime that they'd underperform on any less during an active operation.
This is like giving your sailors food poisoning every week to make them tougher. You just make them weaker instead. And when the time comes, you don't get soldiers capable of eating rotten food. You just get weak people.
Agreed. I could see putting people in that situation for 1-2 week every few months just so they know what it's like and can handle it when it comes up, but running everyone ragged is just going to lead to lots of preventable problems for no gain that I can see
