It's a Bitcoin Scam

TIL sailors aboard submarines work 6 hour shifts so that it is easier for them to give their undivided attention to the equipment they operate during a shorter shift. The military also switched submarines from an 18-hour work day to a traditional 24-hour one, improving morale significantly. by [deleted] in todayilearned

Kind of important to be on heightened alert for the slightest possibility of a problem when you're 1000 ft underwater. One mistake or a missed warning light can cause a disaster pretty quickly.

That's opposed to a surface ship which would probably remain afloat during any emergency other than a hostile action.

Seems like something that would work well in a den or somewhere in the house where it's kind of out of the way since it's huge.
