A tub boat was a type of unpowered cargo boat used on a number of the early English and German canals. The English boats were typically 6 m (19.7 ft) long and 2 m (6.6 ft) wide and generally carried 3 long tons (3.0 t; 3.4 short tons) to 5 long tons (5.1 t; 5.6 short tons) of cargo, though some extra deep ones could carry up to 8 long tons (8.1 t; 9.0 short tons). 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.
One tub-boat is preserved in the Blists Hill Victorian Town museum.
