Block


In maritime context, a block is a pulley or a system of pulleys mounted on a ship's deck, mast, or yard, used to change the direction of a rope or cable and to increase the mechanical advantage of a hauling or lifting operation. Blocks are made of various materials such as wood, metal, or synthetic materials, and come in different sizes and shapes depending on their specific use. They are essential components of rigging systems and are used for a variety of tasks such as hoisting sails, lifting cargo, and controlling the movement of heavy equipment. The efficiency and safety of a ship's operations depend on the proper selection, maintenance, and use of blocks.
