It's actually much worse than that. At sea, those with operational responsibilities don't work a normal day or week. Not only are you working over 100 hours, but you destroy your circadian rhythm. While it shows 23 hours of sleep in every 72, that's under optimal conditions when things aren't breaking and operations / drills aren't interrupting everything. This is what my full 72 hour rotation looked like in 5 on / 10 off: DAY 1: 0600: Wake up, shower/shave, breakfast, make rounds to Engineering and Combat to get situational updates, head to bridge for turnover. 0700-1200: Watch 1200-1300: Lunch, maybe some personal time 1300-1700: Work, maybe catch a nap for an hour (1) 1700-1800: Dinner, or skip it for a workout 1800-1900: Intel Brief 1900-2100: Work, personal time, or nap 2100-2200: Coffee, round for watch, get to bridge early to adjust eyes 2200-0200: Watch DAY 2: 0200-0700: Sleep (5) 0700-0800: Breakfast 0800-1100: Work 1100-1200: Lunch and rounds 1200-1700: Watch 1700-1800: Dinner 1800-1900: Intel brief 1900-0100: Sleep (6) DAY 3: 0100-0200: Coffee, rounds, more coffee, turnover 0200-0700: Watch 0700-0800: Breakfast 0800-1200: Work, maybe nap (3) 1200-1300: Lunch 1300-1600: Work 1600-1700: Dinner, turnover 1700-2200: Watch 2200-0600: Sleep (8)
