Which term indicates the upper edge of a vessel's side?

The term "gunwale" refers specifically to the upper edge or rim of a vessel's side. It serves various important functions, such as providing structural support to the boat's hull and helping to keep water from entering the interior of the vessel. The gunwale is often a place where accessories like rod holders or cleats can be mounted, enhancing the vessel's functionality.

In contrast, "bow" denotes the front section of a boat, while "hull" refers to the main body of the vessel, which includes the underwater portion. "Starboard" specifies the right side of the boat when facing forward, showing how these other terms relate to different parts of a vessel without overlapping the definition of the gunwale. Understanding these distinctions is key for safe and effective navigation and operation of a boat.
