Why not just define it the simplest way and the way the terms are actually used (port/left and starboard/right), by looking from stern to bow, or along the current heading (where the ships head/bow) is pointing. In the case of unsymmetrical vessels as well, the two halves are never separately assembled. In general, most ships are symmetrical about their centerline on both sides. This has proven to be the ideal design that allows for the least resistance in moving a ship. Although the terms port and starboard started off on-board English ships several centuries ago, they have found their way into every mariner’s life. Without them, navigation would be a nightmare, and accidents would be frequent occurrences.

However, certain experiments conducted in recent times at hydrodynamic testing facilities have pointed out that specific vessels that are unsymmetrical can have better performance parameters compared to their symmetrical counterparts. These steering oars functioned as the rudders of the craft and had to be expertly manoeuvred. Hence, it was easier to have the steering oar on the right-hand side so that the sailor was facing forward comfortably. Thus, only small red and green stripes are present for the pilot to judge the location of the vessel and the area that they need to land on. The port side is the ship’s left side when looking forwards towards the bow of the ship. The starboard is right side of the ship when facing the bow.This ambiguity persisted for a considerable period until it was regularized around the 16th century AD. An important point to keep in mind is that ships do not take drastic changes in direction. Considering the enormous size of these vessels, it may take an average of a few kilometres for the ship to execute a direction change of a few degrees. Thus, commercial cargo and passenger-carrying vessels generally limit direction changes to within 45⁰ on the port and starboard sides. When looking from the bow to the stern, the port lies on the right side while the starboard side lies on the left side.” In this article, we will cover the concept of port and starboard and the various uses of these terms throughout maritime history. Origin of the Terms – Port And Starboard As right and left are ambiguous due to the lateral inversion of perspective, there is a higher risk of a collision without the use of proper terms. Directions in Navigation and Steering

These directions must be passed as X degrees to the Port or Starboard. Here, X can take values ranging from 0⁰ to 180⁰ and indicates how much the ship should turn in the relevant direction.Also, considering that poor visibility could lead to difficulty in identifying the port and starboard sides of vessels, colour codes were assigned based on accepted conventions. These are discussed in greater detail in the next section. The terms port and starboard are used instead of left and right since port and starboard never change as they are unambiguous references that are not affected by a mariner’s orientation. Hence, these nautical terms help mariners in avoiding confusion and improve onboard safety. This led to the left side being called the larboard, based on the corruption of the old English term for loading. However, it was common to confuse the terms larboard and starboard while sailing, as they sounded similar. Thus, larboard was later replaced by the term port. This also aided in other terminology, as it was the left-hand side that was moored to the port. These terms also become useful while passing messages between ships. For instance, instead of mentioning that a vessel would be passing to the right or left of a ship, the terms starboard and port can be used.

This definition of port and starboard ensures that these directions are unique irrespective of the position of the concerned party. When facing the other vessel, if the red light is on the right and the green is on the left, the indication is that the vessel is approaching your position. Studies have shown that most pilots turn to the left when faced with an aborted landing and even during accidents. This logic is followed even while driving on roads in some countries. Most cars have steering wheel positions that enable the driver to safely pull over to the left instead of heading to the right where there is incoming traffic. Incorrectly passing information has led to major mishaps in the past. So, although both instructions put the vessel in almost the same position, care must be taken when using them. In addition to manoeuvring, the terms port and starboard are also used to spot and convey the location of an object, mainly on warships.

Along with the port and starboard nautical terms, colours are also used to aid in navigation, especially during night manoeuvres. In general, 0⁰ to either side does not result in any change in direction. For instance, 90⁰ to the starboard indicates that the vessel must now proceed in a direction perpendicular to the initial direction and on the starboard side.

When commandeering a vessel of massive proportions, it is important that information is correctly passed between the various systems of the ship. Ships also have white lights on the masthead and stern. These, combined with the red and green lights, make it easy to identify the ship’s direction at night.
