Port vs. Starboard: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Port refers to the left side of a ship when facing forward, while Starboard denotes the right side.
Key Differences
Port and Starboard are nautical terms used to describe the orientation of a ship or boat. Port indicates the left side when one is facing the bow (front), while Starboard refers to the right side. These terms help in avoiding confusion that can arise from using left and right, which change based on direction one is facing.

Historically, Port was known as 'larboard', which could be easily confused with Starboard during communication over the noise of the sea. Thus, the term Port, which derives from the practice of docking ships on the left side, became standard. Starboard comes from the Old English term 'steorbord', referring to the side where the ship's steering paddle was placed.

The importance of Port and Starboard is crucial for navigation and maritime safety. Knowing the difference helps in understanding sailing rules, especially when navigating crowded or complex waters. Port is typically marked with a red light and Starboard with a green light on ships to aid in night navigation.
