Mooring

Mooring. To moor is to confine or secure a ship, otherwise than by a single anchor, in a particular situation. Mooring may be effected either by letting go two anchors in such a manner that the strain on the two is equally divided, or by shackling one or more of the ship's cables to a buoy, or to anchors that have been previously placed in position, or to "chain mooring." These are an assemblage of anchors, chains, and bridles laid athwart the bottom of a river or harbour for the purpose. When two anchors are dropped by a ship, the cables of both are, as a rule, afterwards shackled together, and from the point of union a single cable is led in through one hawsehole.
