  • Horizontal Windlass: Has a horizontally mounted motor and gypsy. This type is often easier to service and is preferred on larger boats where deck space allows.
  • Capstan Windlass: Primarily used for hauling lines rather than anchor chains. It has a smooth rotating drum and is useful for mooring or docking.
  • Manual Windlass: Operated by hand using a crank or lever. Suitable for small boats or as a backup system.

Each mechanism functions by engaging the anchor chain or rope with a rotating component that winds the rode (the anchor line) onto a drum or gypsy, enabling controlled deployment and retrieval of the anchor.

Components of a Windlass System

A windlass system consists of several key components that work together to manage the anchor rode efficiently:

  • Gypsy (Wildcat): The notched wheel that grips the anchor chain, allowing it to be pulled in or let out.
  • Motor: Powers the rotation of the gypsy. Motors can be electric, hydraulic, or manual.
  • Drum: Present in capstan windlasses, it handles rope or line instead of chain.
  • Brake: Controls the descent of the anchor, preventing it from running out uncontrollably.
  • Clutch: Engages or disengages the gypsy from the motor, allowing manual operation if needed.
  • Chain Locker: Storage area below deck where the anchor chain is stowed.

Proper integration of these components ensures smooth operation and safety during anchoring procedures.

Operation and Control of Windlasses

Operating a windlass involves careful coordination to safely raise or lower the anchor. Modern windlasses often include remote control capabilities for ease of use from the helm or deck.

Key operational aspects include:

  • Power Source: Electric windlasses typically run on the boat’s DC power, while hydraulic models rely on the vessel’s hydraulic system.
  • Control Interfaces: Controls may be foot switches, hand-held remotes, or panel-mounted buttons.
  • Speed Settings: Variable speed control allows operators to manage the anchor rode carefully, especially in strong currents or heavy weather.
  • Safety Features: Automatic brakes and limit switches prevent accidents and protect the equipment.

Operators must always monitor the anchor rode tension and ensure the windlass is properly engaged to avoid damage or loss of the anchor.
