The Navy Lark

Captain Povey has built a reputation for shutting down redundant naval bases. He now has his eye on the minesweeping detachment on Boonzey island (55.5 miles from Portsmouth, a Channel Island) He is told tales of finding many mines in the sea there and not believing them goes out on the Compton minesweeper. The crew were supposed to find "Bessy", a mine-shaped object used to collect Lifeboat funds but found a real mine instead.
