What is the term used to describe the area from the center line toward either side?

The term "beam" refers specifically to the width of a vessel at its widest point, which is at right angles to the centerline. When describing the area from the centerline toward either side of a boat, "beam" accurately captures the lateral extent of the vessel. This is a crucial concept in maritime terminology as it helps to define not only the physical structure of the boat but also how it interacts with water and other vessels in navigation and docking scenarios. Understanding the beam is essential for safe maneuvering and for comprehending the boat’s balance and stability in various conditions.
