Havighurst, Walter "The Tides of Lundy"

Another Havighurst World War 2 tale, this one set aboard a small converted British herring trawler engaged in minesweeping / submarine duties off the Bristol Channel. Havighurst’s chief character is the vessel’s commander, Lt. Leonard Macedon, the only Royal Navy man aboard the fictitious St. AGNES. He’s inherited an unhappy ship, one in which deck crew and engineers rarely cooperate. A furious battle with a German U-boat changes all this and as a result his civilian crew rapidly – and enthusiastically – learn that teamwork is necessary if they are to wage successful sea battle.
