A roadstead (German: reede; French: rade; Russian: рейд) is a body of water sheltered from rip currents, spring tides or ocean swell outside a harbor where ships can lie reasonably safely at anchor without dragging or snatching while waiting for their turn to enter a port of call.[1][2] It can be open or natural, usually - estuary-based, or may be created artificially.[3] In maritime law, a "known general station for ships, notoriously used as such, and distinguished by the name".[4] Charts and nautical publications substitute roadsteads for roads.[5]
