The port-side is the left side of any nautical vessel or ship. The left side of a ship is permanently called the port side.

Portside and starboard stay the same on every ship, vessel and boat and it is also used for aircraft. They are used for the mariner and crew’s orientation. The nautical terms of Portside and Starboard are used instead of left and right to avoid any confusion particularly over radio communications. By recognising Portside and Starboard you can determine the way the ship is sailing you will always know which way is left and which way is right.

When looking forward toward’s the bow of a ship, portside will always refer to the left of the ship. This makes Starboard the right. When looking the opposite way towards the Stern of the ship Portside will be right and Starboard will be left. Therefore the best way to determine whether you are on the Portside the left of the ship is to work out which is the rear of the ship (stern) or the front of the ship ( bow ).

The left side is called ‘port’ because ships with steerboards or star boards as in history ships would dock at ports on the opposite side to the steerboard. This makes the steerboard or starboard the right. As the right side was always the steerboard side or star board side, the left side has to be the port side.

In the early days of ships and boating, boats were steered and controlled using a steering oar. As naturally most sailers where right handed the steering oar was placed through the right side of the ship. Sailors years ago began calling the right side of the ship the steering side. This word Steer soon became “starboard”. The other side the known now as Portside was known as “larboard”, or “the loading side.” The larboard would be were crew and goods were loaded on to the ship or boat.

As the size of ships grew so did the steering oar. This made it easier to make a ship dock on the side opposite the oar ( starboard ).

Over time it became evident that word “larboard” was too easily confused with “starboard”. The words sound the same during communication over radios.

Portside and Starboard History

In 1844 Admiralty issued an order, stating that: ‘The word ‘Port‘ is frequently substituted for the word ‘Larboard‘, and as the distinction between ‘Starboard‘ and ‘Port‘ is so much more marked than that between ‘Starboard‘ and ‘Larboard‘, it is the Lordships’ direction that the word ‘Larboard‘ shall no longer be used.’

Thus Larboard was then replaced with the word “port” or Portside as this was the side that faced the port thus it easier to distinguish.
