Definition

An area of relatively uniform water depth with no cables, pipelines, or hazardous obstructions present on the seafloor, in which vessels anchor or may anchor.

Description

Anchorage areas are additionally determined by: the depth of water in comparison to the tidal range; the material of the seafloor bottom; local environmental effects of wind and currents; and proximity to hazards to navigation, adjacent ships, and harbor traffic lanes. Although the anchorage refers to an identified area along the water surface, its physical structure is considered to be the material and condition of the seafloor below. An anchorage can be physically damaged by natural events (for example: an earthquake or tsunami) by which the preferred seafloor bottom type can change, or hazardous obstructions can be created or moved into the anchorage area.
