burtoning

Burtoning is a cargo-handling system that uses a sling rigged between two derricks or masts to lift and move cargo. This method was common in the 20th century, particularly for serving cargo hatchways. It allowed for precise control of a single lifting hook, enabling both vertical and horizontal movement of cargo between the ship's hold and the pier.12

While effective, burtoning has largely been replaced by systems better suited for specialized cargoes, such as container ships and bulk carriers. However, it may still be found on ships designed for handling very heavy objects.2
