Wrong answer...especially in peace time!
I was in the Navy for about 10 years...served on the USS Saratoga and USS Inchon.
Unlike a cruise ship, crewmembers are berthed in very close quarters....not staterooms. There may be as many as 100 personnel on a berthing compartment, normally two or three racks high and, if an adjacent berth, only a opaque curtain separates shipmates. A breeding ground for rapid transmission of a contagious disease.
If this had happened in war time, this risk may have been acceptable...but we're not at war.
So, you guys criticizing that skipper don't know what the **** you're writing about...do you? Would you like to write those letters to the husbands, wives or parents of the men and women who died?
