Frapping is a term used in sailing that refers to the act of securing a sail tightly to prevent it from flapping in the wind. This is often done when a sail is not in use or during rough weather to protect the sail and the boat. Proper frapping helps maintain the integrity of the sail and ensures safety on board. In addition to sailing, frapping can also refer to a technique in rigging where ropes or lines are wrapped around an object to hold it in place. This method is commonly used in various applications, including construction and outdoor activities, to provide stability and prevent movement.
