Project history: The belief that Q-ships or decoys were the best counter to the U-boat threat led to an Admiralty order in December 1916 to complete 10 P-boats with a mercantile appearance, like the 'Flower-Q's. Although known for a while as PQ-boats the term PC-boat was finally chosen, and a further 10 were ordered, PC65-70 in January 1917 and PC71-74 in June. They were fully integrated in to the Q-ship system and used false names (as shown in the table). There were severe topweight problems in fitting false upperworks and derricks etc to such a small hull, and many had wooden girdling added to improve stability.
