The Mersey Flat's Role in the Coal Trade
Coal, mined from pits in Lancashire, played an important role in the industrialisation of North West England and Mersey flats were used to transport this valuable commodity from local collieries to the booming urban centres. Sailing flats, first appearing on the River Mersey in the early 18th century and capable of carrying eighty tons of coal in their holds, were of such importance to the mining industry that a series of river navigations and canals were built to accommodate vessels of this size. These flat-bottomed barges, equipped with a fore-and-aft rig that was attached to a single mast, only required a crew of three to operate. Lancashire, home to the largest coalfield in North West England, possessed a number of bell pits and drift mines at the beginning of the 18th century that provided fuel for the burgeoning industries in the region. Shallow mines such as these, prone to flooding and eventual collapse, could only be used to extract coal that was near to the surface. Enginee
