Around the mid-18th century, goods and passengers began to be transported by ship between London and Whitstable, and a toll road was built to the cathedral city of Canterbury. These improvements in transport led to the town's development as a seaside resort; the first advertisements for bathing machines at Whitstable appeared in 1768. In 1790 the manor was sold to private landowners, and three years later the rights to harvest the oyster beds were bought by the newly established Company of Free Fishers and Dredgers of Whitstable, the successor to the Whitstable Company of Dredgers. Between roughly 1775 and 1875 the well smacks or early longliners out of Barking and other local fishing ports would collect lugworms and whelks from Whitstable's bait-diggers and dredgers before beginning their tour for prime fish north to Iceland. Whelks suspended in net bags in the well could live for a while due to circulating water.
