The term starboard side refers to the right-hand side of a vessel when facing forward. This specific nautical designation has governed maritime navigation for centuries, yet its origins are far more tangible than a simple directional label.
The Historical Roots of "Starboard"
To understand why is it called starboard side, one must look back to the evolution of seafaring vessels. Early mariners, primarily steering with a single oar, naturally preferred the right side for control. In Old English, this steering side was called "stéorbord," a direct combination of "stéor" (meaning steering) and "bord" (meaning board or side). This linguistic origin directly answers the core question of why is it called starboard side, linking the word directly to the physical action of steering.
Steering Oars and Starboard Dominance
Long before modern rudders were invented, ships were maneuvered using a large steering oar mounted on the stern quarter. Because most sailors were right-handed, this oar was consistently placed on the right side of the hull. This practice was so universal that the right side became permanently associated with the location of the steering apparatus. Consequently, the question why is it called starboard side is intrinsically tied to this historical practice of mounting the steering gear on the right.
Contrast with Port Side
As maritime traffic increased, the need to standardize communication became critical to avoid dangerous misunderstandings. Vessels required a universal rule for passing, and the right side was designated as the primary contact side. This created the necessity for the opposite term. The left side, where loading docks were often located to avoid interference with the steering oar, became known as "larboard." However, due to the phonetic similarity between "larboard" and "starboard," which could cause confusion in noisy or stressful situations, the maritime community eventually adopted "port" for the left side, referencing the side of the ship that faces the harbor.
Why the Shift from Larboard to Port?
Phonetic Clarity: "Larboard" and "starboard" sound too alike, leading to errors in high-pressure scenarios.
Harbor Relevance: The port side is the side facing the dock, making the term intuitive for loading operations.
Universal Adoption: The shift to "port" ensured clear communication between ships from different nations and languages.
The Enduring Legacy
Although the steering oar is a relic of the past, the terminology persists. Modern ships now feature centrally mounted rudders and advanced navigation systems, yet the tradition of referring to the right side as starboard remains deeply embedded in naval protocol. The answer to why is it called starboard side is therefore a historical one; it is a linguistic fossil that preserves the ingenuity of early sailors who solved the problem of navigation with simple, practical solutions.
Global Consistency in Maritime Law
International regulations, such as the "Rules of the Road" defined by the International Regulations for Preventing Collisions at Sea (COLREGs), strictly enforce the use of starboard and port. These laws dictate that a vessel gives way to the right, reinforcing the starboard side's role as the primary reference point for safety. Understanding this etymology is not merely academic; it is fundamental to the safe and efficient operation of any vessel, ensuring that every captain, regardless of nationality, shares a common language.
