The Keelmen of Tyne and Wear were a group of men who worked on the keels, large boats that carried the coal from the banks of both rivers to the waiting collier ships. Because of the shallowness of both rivers, it was difficult for ships of any significant draught to move up river and load with coal from the place where the coal reached the riverside. Thus the need for shallow-draught keels to transport the coal to the waiting ships. The keelmen formed a close-knit and colourful community on both rivers until their eventual demise late in the nineteenth century.
Coal began to be exported from the River Tyne from the mid-thirteenth century onwards. The first recorded shipment of coal from the River Wear was in 1396. The pits from which coal was then exported were near the riverside so that as little effort as possible was required to load it. The coal was carried to London and elsewhere in colliers; small wooden sailing ships that sailed down the east coast. At this time neither the Tyne nor the Wear were easily navigable for ships of significant draught. The mouth of the Tyne was obstructed by Herd Sands, Bellehues Rock and a bar that ran across the mouth of the river. Further up river a ship might run aground in various shallows and the stone bridge at Newcastle prevented colliers from reaching coal deposits further up river. Both rivers were very shallow near the banks, which made the approach difficult so coal was loaded into the shallow-draught keels to transport it down river.
The keels were wooden boats with a pointed stern, so that the bow and stern looked almost the same. They were of shallow draught so that when fully loaded they drew only four and a half feet. The keels were forty feet long and at least 19 feet wide amidships: a very broad configuration. In 1266 the standard load of a keel was set at 20 chaldrons (wagonloads) or approximately 17 tons. After 1497 the keel load was frequently increased, until in 1635 it was set at 21.1 tons. A chaldron was a horse-drawn wagon containing 17 cwt of coal. Keels were supposed to be measured by the Kings Commissioners and given a load mark to show when they were full. The keels had a single mast with a square sail attached to a yardarm and two large oars. They had no rudder and so a large sweep was used for steering when the keel was under sail. The oars were used to row when the wind was not favourable. There were also two iron-shod poles for polling the keel through any shallows. The floor of the hold was only two feet below the gunwale to allow for easy loading. The coal was piled high above the top of the hold with wooden boards used to prevent the cargo from sliding. Each keel was manned by a skipper, two crewmen and a boy, known as a ‘pee dee’. The meaning of this title is unknown.
