    General Notes.- All built under Emergency War Programme. Were designed to relieve destroyers of patrol and escort work and submarine hunting. Outline scheme for these boats stipulated; minimum size consistent with sea-keeping qualities, simplicity of construction, and adequate speed to run down submarines: also shallow draught; low upperworks to reduce visibility; and economy of fuel. Built of mild steel, but with hard steel stem for ramming submarines. Large rudder area and hull strongly cut up aft to give rapid turning. Proved very useful boats and an excellent anti-submarine type in all weathers. Those converted to Decoy Ships or " Q-boats " listed as PC boats on the preceding page.
