Tars and spars (1946)

Howard Young is a coast guardsman who has been on shore duty for three years despite his efforts to be sent into action. His nearest approach to sea duty was on a harbor-moored life raft for 21 days as part of an experiment with a new type of vitamin gum for the government. He meets Christine Bradley, a SPAR, sent to take over his communications job and, by things he leaves unsaid, she thinks his life-raft experience was the result of a ship-wreck at sea.
