A tub boat was a type of unpowered cargo boat used on a number of the early English〔(List of tub boat canals )〕 and German canals. The English boats were typically long and wide and generally carried to of cargo, though some extra deep ones could carry up to .〔(Definition )〕 They are also called compartment boats or container boats. The main virtue of tub boats was their flexibility. They could be drawn in trains of 3-10 or more boats using horse power, or later steam tugs, where the number of boats was varied according to the type of cargo. Tubs could be lifted more easily than larger boats and tub boat lifts and inclined planes were developed as an alternative to canal locks, particularly in or near a colliery or similar industrial works. At a lift the train could easily be divided, the boats lifted individually, and the train reassembled afterwards. Sometimes the boats used snug-fitting non-waterproof inner containers which could be more easily lifted out. Because of their small size, the canals that were built for tub boats could also be smaller, saving considerable construction cost. The first use of tub boats in England was on the Bridgewater Canal. Other notable uses were on the Shropshire Union Canal and the Bude Canal. One tub-boat is preserved in the Blists Hill Victorian Town museum. In later years, larger versions of tub boats included the Tom Pudding on the Aire and Calder Canal and the Hargreave barge used on the same waterway. ==List of Tub Boat Canals== *Bude Canal, Cornwall *Chard Canal, Somerset *Cyfarthfa Canal,〔http://map.coflein.gov.uk/index.php?action=do_details&cache_name=cG5tcnNuYW1lLEN5ZmFydGhmYSBDYW5hbF9zZWFyY2h0eXBlLGFkdmFuY2VkX29yYQ==&numlink=232778#tabs-4〕 Merthyr Tydfil, Wales *Donnington Wood Canal, East Shropshire *Dukart's Canal, Tyrone, Northern Ireland *Grand Western Canal, Devon *Ketley Canal, East Shropshire *Lydney Canal, Gloucestershire *Shropshire Canal, East Shropshire *Torrington Canal, Devon *Wombridge Canal, East Shropshire 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「tub boat」の詳細全文を読む スポンサード リンク
