What is the definition of the hull of a vessel?

The hull of a vessel is best defined as the main body of the vessel. It serves as the structural framework that provides the shape and buoyancy necessary to support the vessel while it is floating in water. The hull is designed to displace water and can come in various styles and shapes, depending on the type of vessel and its intended use—whether for speed, stability, or cargo capacity.

Understanding the hull's primary function as the main body helps in recognizing that it is essential for the overall integrity and performance of the vessel. The hull does not include components such as the propulsion machinery or technical control systems, which are separate systems that facilitate movement and navigation. While buoyancy components may be integrated into the hull, it is not limited to just those parts; thus, the broader definition as the main body is more accurate.
