Which term describes the body of a vessel or boat?

The term that describes the body of a vessel or boat is "hull." The hull is the main structure of the boat that provides buoyancy and stability. It is the part of the vessel designed to float on the water, protecting the interior components and ensuring safe passage over waves and other water conditions. The hull can be constructed from various materials, including wood, fiberglass, and metal, and comes in different shapes depending on the type of boat and its intended use, such as sailing or motor boating.

Other terms mentioned are related but do not refer to the body of the vessel. The gunwale refers to the upper edge of the sides of the hull, which provides a structural framework and is where equipment or ropes are often secured. A cleat is a device on a boat used to secure ropes, and a propeller is a device that propels the boat through the water. These terms are essential for understanding various aspects of boating, but they do not define the central structure of the boat like the hull does.
