Why do ships have two anchors?

Strong winds, currents, and waves can generate big forces that can drag a ship even if anchored. Sometimes ships, and especially small boats, need to set two anchors to hold them in place. … Almost every ship carries two anchors, one in the starboard hawsepipe and the other in the port hawsepipe.
