Navigational Terms in the US Navy: Port, Starboard, and Beyond

The US Navy's use of navigation terms such as 'port' and 'starboard' is a critical aspect of maritime operations, especially in low-visibility conditions. Understanding these terms is essential for effective communication and coordination among crew members.

Understanding Port and Starboard

In the US Navy, the terms 'port' and 'starboard' are used to specify the left and right sides of the ship, respectively, when facing the bow. This terminology ensures clear and consistent references, which is crucial for avoiding confusion in various scenarios, particularly in low-visibility environments.

For instance, 'port' refers to the left side of the ship when facing forward towards the bow, and 'starboard' refers to the right side. This standardization makes it easier for crew members to communicate without ambiguity, whether they are discussing steering directions or pointing out specific locations.

Why Use Port and Starboard?

Traditionally, the US Navy uses a system of terms that is distinct from everyday English. This is because port and starboard are independent of the observer's position, which can be particularly helpful in large ships where the direction of movement (from bow to stern or vice versa) may not be immediately apparent from the scenery.

In a large ship, facing the bow might not always indicate whether significant movement is occurring towards the bow or away from it. For example, when a ship is turning, the direction of the starboard and port sides changes relative to the observer. Therefore, using 'port' and 'starboard' ensures that everyone is referring to the same fixed points, regardless of these relative changes.

Compatibility with Maritime Standards

While the US Navy uses 'port' and 'starboard' for its internal communications, it is important to note that these terms are widely used in the maritime industry. In fact, all maritime watercraft employ these terms, along with a standardized system of lighting to indicate navigation signals.

Navigation lights, such as red for port, green for starboard, and white for the forward and aft masts and stern, provide clear visual cues. A typical setup on a ship includes a white light on the forward masthead and another on the stern to indicate the direction of travel. These lights, combined with the 'port' and 'starboard' terms, form a comprehensive system for safely navigating through waters.

Adoption in Military Services

The usage of 'port' and 'starboard' in the US Navy is rooted in the broader naval tradition. While these terms have specific meanings, there are also other nautical terms like 'aft' and 'bow' that are commonly used.

These terms, along with 'forward' and 'aft,' are used to specify directions in a ship, while 'overhead' and 'deck' are used for levels on a ship, similar to 'ceiling' and 'floor' in a building. Ladders and stairs on a ship are referred to as 'ladders,' emphasizing the importance of this unique linguistic system.

The use of specific terms and language within military services like the Navy, Army, Marines, and Air Force is crucial for maintaining a sense of organizational identity and a shared understanding of operations. This sense of belonging and coherence is vital in the dynamic and often high-stakes environment of the military.
