General Notes.-All built under Emergency War Programme. Design as P-boats, but these craft were converted or modified while building, to act as Submarine Decoy Vessels or " Q-boats." The after 4 inch gun was hidden behind various forms of dummy deck loads, e.g., bales or packing cases of merchandise, trusses of hay: in a few boats it was located within a collapsible pantechnicon furniture van, or under a dummy boat built in folding sections. It was expected that, on account of shallow draught, torpedoes fired by U-boats would under-run these PC-boats, while, if hit by torpedo, bulge protection and special fillings would keep them afloat long enough to destroy the U-boat.
