Capstan Meaning in Sailing

A capstan represents a large vertical cylinder used for pulling heavy ropes or anchor chains. This mechanical device rotates to provide the power needed to lift massive weights from the sea. Sailors wrap several loops of line around the drum to create the necessary friction. On older ships the crew turned the drum manually using long wooden removable bars. Modern versions use powerful electric or hydraulic motors to do the heavy work on deck. One specific example involves a sailor using the capstan to pull the anchor out of mud. The rotating cylinder winds the thick chain and pulls the boat toward the submerged weight. This tool allows a small crew to handle forces that would be impossible by hand. The drum features a ratcheting mechanism to prevent the heavy load from slipping back down. Keeping the metal surface clean ensures the rope does not get stuck during the operation. This equipment remains a vital part of the deck machinery on every large sailing ship.
