Anchor buoy, George Stebbing, c. 1820 - c. 1840
An anchor buoy was floated on the water’s surface to prevent other ships from sailing over the anchor chain of a moored ship. It also marked the location of the anchor and allowed it to be recovered if the cable broke or had to be cut. This anchor buoy, designed by the Englishman George Stebbing, was lighter and had a longer life than those previously used.
