The convention of steering vessels from the starboard side (right-hand drive in automotive terms) originated in the age of oar-powered ships. With oars being the primary method of propulsion and maneuverability, most sailors, being right-handed, would have held the steering oar in their stronger right hand, positioning themselves on the starboard side of the stern for optimal leverage and control. This naturally placed the steering oar on the vessel’s right, establishing a pattern that persisted as ships transitioned to rudder-based steering systems.
Standardizing the steering position offered substantial advantages in navigation, especially in busy waterways. Consistent helm placement reduced the risk of collisions in passing situations, simplifying navigation in confined spaces. Furthermore, this established convention contributed to the development of standardized maritime rules and practices, enhancing safety and efficiency at sea. The enduring influence of this historical practice can be seen in the design and operation of modern vessels, where steering controls typically remain on the starboard side.
