Drakes Island lies directly at the mouth of the River Tamar and before the Breakwater was built a number of ships that were blown into Plymouth Sound by southwesterly gales came to an untimely end on her rocky shores.
On the northern side of the Island is Asia Shoal (5 to 18m), where there is a range of marine life including sponges, hydroids, burrowing anemones. Scallops and plaice are often seen here.
On the southeast side of the Island is Pilot Shoal (3 to 9m). The seabed consists of primarily sand with a number of rocky outcrops, where there is a range of marine life including sponges, hydroids, burrowing anemones.
