Starboard Beam

The side of a vessel that is directly to the right, at a 90-degree angle from the centreline, when facing forward.

The term starboard beam is used to describe a specific location relative to a vessel’s orientation. Starboard refers to the right-hand side of a vessel when facing the bow (the front), while beam refers to the widest part of the vessel, which is perpendicular to the centreline. Therefore, the starboard beam is the area directly to the right of the vessel, at a 90-degree angle from the bow. This term is often used in navigation, communication, and situational awareness to describe the relative position of other vessels, objects, or hazards. For example, if another vessel is said to be on your starboard beam, it means that it is located directly to your right, at the widest point of your boat. Understanding the concept of the starboard beam is crucial for maintaining proper situational awareness, especially when navigating in crowded or narrow waterways, as it helps mariners quickly and accurately communicate the position of other vessels or obstacles. Additionally, knowing the position of objects relative to the starboard beam can assist in making informed decisions about course changes, speed adjustments, or collision avoidance.
