Boat trackers refer to those who track or row the boat for others and take it as a profession. When the carrying of a whole set of things such as coal, lumbers, agricultural and sideline products as well as daily commodities greatly relied on water transportation, boat trackers played a key role at that particular time. They would bend their body and drag the halter through their back with great effort to move along. Apart from tracking the boat, they also chanted the boatman work song with their hoarse voice.
