These robust, removable pegs offer a traditional method for securing running rigging on smaller sailing vessels. Acting as temporary anchors, they efficiently hold lines under load, allowing sailors to control sails, such as the mainsail or jib, effectively. For instance, a line controlling the angle of a sail might be wrapped around a pin to maintain a desired setting.
Their use provides a reliable and straightforward mechanical advantage system, particularly valuable on small boats where space and weight are crucial considerations. Historically prevalent on larger ships, this approach has been retained on smaller craft due to its simplicity, durability, and ease of maintenance. Furthermore, it avoids the complexities associated with more modern mechanical clutches and winches, proving advantageous in environments where repairs might be challenging.
