What does the term "hull" specifically refer to?

The term "hull" refers specifically to the outer body of a vessel. This is the part of the boat that is designed to float on water and is primarily responsible for providing the necessary buoyancy to keep the vessel afloat. The hull is also crucial for the boat's stability, structural integrity, and overall design as it affects how a boat handles on the water. It protects the insides of the vessel from the elements and potential water ingress. Understanding the function and design of the hull is essential for safe boating practices, such as knowing how to maintain and inspect it for any damage that could lead to safety issues while on the water.
