Electric Windlass

Understanding the Functioning of a Maritime Electric Windlass

An Electric Windlass is an integral device typically used on maritime vessels to facilitate the convenient lifting or lowering of heavy kit like anchors or fishing trawl equipment. This device operates via an electric motor that transmits power through a gear system, turning the horizontal or vertical axis, which in turn spins the drum or chain wheel. When power is applied, the Electric Windlass uses this to haul the attached rope, chain, or cable, significantly reducing the physical effort otherwise required by the crew.

Differentiating between a Winch and a Windlass

It is common to confuse a windlass with a winch, but these are actually two distinct devices with similar functionalities but different applications. A winch, like a windlass, also helps in lifting or pulling heavy loads, but it does so through a horizontal axis. On the other hand, a windlass operates on a vertical axis. Additionally, while winches are commonly used for various applications on land or ships, windlasses are primarily used for anchoring purposes in maritime contexts. The key difference lies in their construction and orientation, which dictates their specific uses.

The term ‘Windlass’ finds its roots in old Norse language, where 'vinda' means ‘to wind’ and 'ass' refers to a pole or beam. This ancient mechanism was utilized to wind ropes or cables around the pole, making it easier to move heavy objects. The term has since evolved and its current usage in naval terminology specifically refers to the device used for anchoring and is universally recognized across the maritime industry. 

Determining the Correct Size of Windlass for a Boat

Selecting the correct size of windlass for a boat involves considering three key factors: the boat's size, the anchor's weight, and the length and size of the anchor rode. Generally, the rule of thumb is that the windlass should be capable of lifting the anchor and the entire length of rode from the seabed in one smooth operation. A windlass rated at three times the total weight of the ground tackle is typically sufficient for most boats. It is crucial to remember that the right size helps ensure that the windlass functions efficiently and prolongs its lifespan.

In conclusion, an Electric Windlass plays a vital role in maintaining the smooth operation of maritime vessels, particularly in anchoring tasks. Understanding its workings, differentiating it from similar devices like the winch, knowing its terminology origins, and determining the right windlass size for a vessel are fundamental for anyone involved in the maritime sector. Further, the efficiency and safety benefits provided by integrating an electric windlass into a ship's design cannot be overstated.
