Coastal Motor Boats

Coastal Motor Boats

Remembering the lives of those who served on Coastal Motor Boats ( CMBs ). During the First World War, following a suggestion from three junior officers of the Harwich destroyer force that small motor boats carrying a torpedo might be capable of travelling over the protective minefields and attacking ships of the Imperial German Navy at anchor in their bases, the Admiralty gave tentative approval to the idea and, in the summer of 1915, produced a Staff Requirement requesting designs for a Coastal Motor Boat for service in the North Sea. These boats had a high speed, making use of the lightweight and powerful petrol engines then available, and each was crewed by just three men. They were armed in a variety of ways, with torpedoes, depth charges or for laying mines. Secondary armament was provided by light machine guns. The CMBs were designed by Thornycroft, who had experience in small fast boats. Engines were not proper maritime internal combustion engines (as these were in short supply) but adapted aircraft engines from firms such as Sunbeam and Napier. The concept of a small fast boat that could inflict serious damage and quickly escape went on to be developed further with Motor Torpedo Boats ( MTBs ) in WW2.
