What is the body of a vessel commonly referred to as?

The body of a vessel is commonly referred to as the hull. The hull is the main structure of the boat or ship that provides buoyancy and stability, allowing it to float on water. It is designed to withstand various marine conditions and is typically shaped to enhance performance in terms of speed and handling.

In contrast, a cleat is a device used to secure ropes, a bow refers to the front part of the vessel, and a gunwale is the top edge of the hull's side. These terms represent specific parts of a vessel and do not define the overall structure, which is why the hull is the correct term to describe the main body of the vessel. Understanding these definitions is crucial for recognizing various components of a vessel and their functions while navigating or discussing maritime terminology.
