Ha. Reminds me of a story. On one ship we had those photoelectric smoke detectors that would go off because of steam if more than 5 showers were on at the same time. We had a fire alarm panel on the bridge and you had to physically hold the button to silence the alarm while summoning the bosun to go down and bang on doors to get people out of the showers. It would take about 30 minutes standing there holding the button until the alarm would clear.
Long story short the Captain walked in on one mate dozing off on watch with his feet up on the ecdis console. I was talking with the Chief at the time and, after admonishing the watch, the old man walked down to my office to complain about the watch. At one point he looked at the Chief and said “I wish you could rig something up that sounded a goddanm alarm when he tried to sit down on watch”
“Oh, I can do that easy Capt” said the Chief. Then he dialed up the intercom system and made an announcement “This is the Chief, we are running low on water DO NOT use the laundry or showers until further notice”
10 minutes later our VHF’s screeched to life. “Bosun, this is the bridge, the goddam alarm is sounding, tell those assholes to get out of the shower!!”
