Step aboard any sailing yacht and within minutes you'll hear two words that sound like a foreign language: port and starboard. They simply mean the left and right sides of the boat – but there's a good reason sailors don't just say "left" and "right". In this quick guide you'll learn what port and starboard mean, where the words come from, and an easy trick to never mix them up again.
What do port and starboard mean?
- Port = the left side of the boat when you are facing forward (towards the bow). Its navigation light is red.
- Starboard = the right side when facing forward. Its navigation light is green.
"Facing forward" is the key phrase – and it's exactly why these words exist.
Why not just say "left" and "right"?
Because left and right depend on which way a person is looking. If the skipper shouts "something's on the left!" it means one thing to a crew member facing the bow and the opposite to someone facing the stern – a recipe for confusion (and collisions). Port and starboard never change. Starboard is always the same side of the vessel, no matter where you stand or which way you face. On the water, where a clear command can prevent an accident, that fixed reference is essential.
Where do the words come from?
Both words are wonderfully old. Starboard comes from the Old English stéorbord – the "steering side". Before boats had a central rudder, they were steered with a large oar mounted on the right-hand side of the stern, so that became the steer-board side. Because the steering oar was in the way, boats were docked with their other side against the harbour wall to load and unload – the "port" (loading) side. The old term "larboard" was dropped precisely because it sounded too much like starboard.
An easy way to remember port and starboard
Two tricks that stick for life:
- "Port" and "left" both have four letters – if the short word fits, it's the left.
- Port wine is red, and the port-side light is red – a glass of red on the left.
Learn it once and it becomes second nature by the second day on board.
Port and starboard in the rules of the road
These words aren't just jargon – they drive the right-of-way rules. At night, the coloured navigation lights tell you which way another vessel is heading: if you see a green light you are looking at its starboard side, a red light means its port side. And when two sailing boats meet, the one on starboard tack (wind coming over the starboard side) generally has right of way. Knowing port from starboard is the very first building block of safe seamanship. Want to go deeper? Our sailing wiki explains the essentials in plain language.
The best way to learn the ropes is on the water. On a skipper training week you'll use port and starboard for real – and by the end it'll feel completely natural.
Frequently asked questions
Is port left or right?
Port is the left side of the boat when you face forward towards the bow. Its navigation light is red.
Why do sailors say port and starboard instead of left and right?
Because they never change with the direction you are facing. Starboard is always the same side of the vessel, which removes any ambiguity from commands on board.
Which light is on which side?
Red on port (left), green on starboard (right). "Any red port left" is a common way sailors remember it.
Conclusion
Port is left and red, starboard is right and green – and unlike left and right, they never change. It's the first piece of sailor's language every beginner learns, and the foundation for the rules of the road. Ready to put it into practice? Join a sailing trip and pick it up hands-on.
