The reason the right side of a vessel is called the starboard side lies deep within the maritime history of humanity. This specific term, distinct from the simple word "right," originates from the Old English language and the very design of the steering oars that guided early seafarers. Understanding this etymology offers a direct connection to the practical challenges faced by sailors centuries ago, long before modern navigation systems existed.
The Nautical Origin of the Word "Starboard"
To answer why is it called starboard side, one must look to the steering mechanisms of ancient ships. Before the invention of the centrally mounted rudder, vessels were controlled using a large steering oar, or "steerboard," positioned on the right side of the hull. This oar was essential for maneuvering, particularly when docking or turning the vessel. The word itself is a compound of the Old English "stéor," meaning "steer," and "bord," meaning "the side of a boat," literally translating to "the side on which the ship is steered.
Steerboard Evolves into Starboard
As the English language evolved, the pronunciation of "steerboard" changed over time. The transition from "stéorbord" to "starboard" is a classic example of linguistic drift, where pronunciation shifts to make speech easier. The "ea" sound in "steer" gradually softened, and the "d" sound became swallowed, resulting in the modern term "starboard." This linguistic change ensured that the name stuck to the specific side of the ship, even as steering technology advanced.
While the term starboard was solidifying on the right side, the left side of the vessel presented its own historical challenge. Because the steering oar was on the right, the left side was consistently used for loading and unloading cargo, as it was away from the water and the steering mechanism. This side became known as the "larboard," a contraction of "lædbord," meaning "the loading side.
Why Confusion Led to the Adoption of Port
The similarity between "larboard" and "starboard" created a significant safety hazard, particularly in poor visibility or noisy environments where miscommunication could lead to dangerous errors at sea. To eliminate this ambiguity, the maritime community sought a distinct term for the left side. They turned to the direction the ship faced, adopting "port" because it was the side of the vessel that faced the harbor port when docking, allowing for safe and efficient loading operations.
Modern Maritime Communication
Today, the distinction between starboard and port is a fundamental rule of navigation, enforced by international regulations. This standardization ensures clarity whether a sailor is on a centuries-old sailing ship or a massive modern container vessel. The call to "port" for the left and "starboard" for the right remains a universal language on the water, a direct legacy of the physical steering oar that once dominated the right flank of every ship.
Examining the term provides a window into the practical realities of early seafaring life. The placement of the heavy steering oar on the right side was not arbitrary; it was a necessary engineering solution that dictated the flow of the ship. Consequently, the language of the sea developed to reflect these physical truths, embedding the answer to why is it called starboard side directly into the vocabulary of navigation itself.
