Which of the following terms describes a device that aids in holding a sail to the mast?

The correct answer is the term that directly refers to a device involved in the rigging of sails. The term describes a component that assists in managing the sails by securing them to the mast, allowing for better control and handling of sailboats.

In sailing, a sheave is a grooved wheel or pulley through which ropes (like halyards) run. It assists in distributing the load and is crucial in the operation of the rigging systems on a sailboat, particularly for managing sail control. The use of a sheave allows for smoother operation when raising or lowering sails, thus playing an essential role in how sails are held effectively to the mast.

Understanding sail handling is vital in sailing, and knowing how each component interacts within the rigging setup is key to effective sailing practices.
