Vindlass

Vindlass, also spelled windlass in English, is a machine used on boats and ships to wind in or pay out a rope or chain. Its primary role is to handle anchors, though it can also be used for raising nets, lines, or other gear. A windlass typically consists of a drum or axle around which the line or chain coils, a drive mechanism (manual crank, electric motor, or hydraulic unit), and a braking or locking system to hold position. When used with chain, a wheel such as a gypsy or wildcat engages the chain to control motion.

There are two main configurations: horizontal windlasses, where the drum lies parallel to the deck, and vertical windlasses, with a drum oriented vertically. Modern vessels often employ powered windlasses—electric or hydraulic—for easier operation on heavy loads, while small boats may rely on hand-operated units. Safety features may include a chain stopper, pawl, and brake to prevent accidental release and to hold the load when not actively being wound.

Typical uses include anchoring and anchoring-related operations: paying out chain to set or retrieve an anchor, and sometimes handling other heavy lines. In fishing and coastal work, vindlasses can be used to haul nets or gear. Maintenance involves regular inspection of bearings, gears, and the brake, lubrication of moving parts, and ensuring the chain or rope is properly spooled to prevent kinking or snagging.
