I was on a Tin Can for awhile, Gearing Class. We were north of the Aleutians one time in early winter. It was rough enough that the galley was closed. No cooked food.
What was the solution? The storekeepers dug around in some store room and dredged up a case of C-Rations. They opened the hatch, and threw them down the hole. The case was dated 1946, this was in 1976. Pall Mall's and little tiny bottles of Tabasco Sauce. Ham and MoFos, Beans and Babydicks. Hash. Inedible chocolate bars (designed that way). John Wayne can openers. Instant coffee that we used to clean deck plates.
Good times!
