What is a beam on a boat?

A beam on a boat refers to the width of the boat at its widest point. The beam is an important measurement as it helps to determine the stability and spaciousness of the boat. A wider beam generally provides more stability and space on board, but may also increase drag and reduce maneuverability.

The beam of a boat is typically measured from the outermost points on each side of the boat's hull, excluding any protruding features such as rub rails or fenders. Beam measurements are usually given in feet or meters.

Boat designers carefully consider the beam of a boat when determining its hull shape and overall design. A wider beam can provide more interior space for cabins, living quarters, and storage compartments, while a narrower beam may result in a faster, more agile boat.

It is important to ensure that a boat's beam complies with local regulations and safety standards. Overly wide or narrow beams can impact a boat's performance and stability, so it is essential to choose a boat with a beam that meets your specific needs and preferences.
