A CHANT (from ''Chan''nel ''T''anker) was a type of prefabricated coastal tanker which was built in the United Kingdom during the Second World War due to a perceived need for coastal tankers after the invasion of France. Some CHANTs were adapted to carry dry cargos. These were known as the ''Empire F type'' coasters. Although five CHANTs were lost during the war, the majority of the ships saw service post war, lasting into the 1990s. ==Design== The CHANT was developed with experience gained by building the Tug, Inshore and Dock (TID). As with the TIDs, CHANTs were built from prefabricated sections which were manufactured at various factories across the United Kingdom. A total of twenty-eight sections made up into a ship. The largest sections weighed thirteen tons which enabled them to be delivered by road. To simplify construction, they were built without compound curves. All plates being either flat or curved in one direction only, with the exception of the skeg at the stern. All joints were welded, with the final being left unwelded at the factory to enable final adjustment at joints when the ship was assembled by the shipyard.〔 CHANTs were designed with a flat bottom to enable them to ground on beaches. A double hull was used to minimise any chance of leakage. Each CHANT had four sub-divided tanks and was fitted with two derricks and winches.〔 They were not the most stable of ships, and needed to carry plenty of ballast.〔(【引用サイトリンク】title=Fuelling at Sea )〕 CHANTs were assembled at five different shipyards, and launched between February and May 1944.〔 Some cargo version (Empire-F type) were built with a "Chant" prefix name which add some confusion about the real type of vessel (i.e.CHANT 41, CHANT 14, CHANT 39, and CHANT 49 were all Empire-F type despite their initial names. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「CHANT (ship type)」の詳細全文を読む スポンサード リンク
