Where was the first lightship stationed in 1732?

The first lightship, known as the Nore, was established in 1732 at Nore Sand, located in the estuary of the River Thames in England. Specifically, it was anchored 4 miles (6 km) southeast of Shoeburyness.123

Lightships were developed as a solution for coastal navigation in areas where the construction of a permanent lighthouse was considered impractical. These early vessels were typically small, converted merchant or fishing ships that displayed lanterns from their mastheads.23
