What is beam on a boat?

A beam on a boat is the width of the boat at its widest point, typically measured at the widest part of the hull. The beam of a boat is an important measurement as it can affect stability, maneuverability, and the overall design of the vessel.

Boats with a wider beam tend to be more stable in the water and have more interior space for passengers and storage. However, a wider beam can also make the boat more difficult to maneuver in tight spaces or in rough seas.

The beam of a boat is typically listed in the boat's specifications and is an important consideration when choosing a boat for a specific purpose, such as cruising, fishing, or racing. Boat designers and engineers take into account the beam of a boat when designing the hull and deck layout to ensure it meets the intended use of the vessel.
