Here is a clear, practical look at what is starboard on a, covering what matters most and what to check before you decide.
Starboard is the right-hand side of a boat when you are facing the front, which sailors call the bow. The opposite side, the left, is port. The terms stay the same no matter which way you are looking, which is why sailors use them instead of left and right.
Why it matters
If you say “left” on a boat, it depends on where you are standing and which way you face. Port and starboard are fixed to the vessel, so a crew member calling “obstacle to starboard” means the right side of the boat to everyone aboard.
Remembering which is which
- “Port” and “left” both have four letters.
- Port wine is red, and the port navigation light is red.
- Starboard has a green light, and “green” matches “starboard right” in many memory tricks.
Navigation lights
At night, boats show a red light on the port side and a green light on the starboard side. If you see a green light ahead, you are looking at the right side of another boat, so you can tell which way it is heading. A white light at the stern shows from behind.
Right of way basics
In many situations, when two power-driven vessels meet on crossing courses, the vessel that has the other on its starboard side must give way. That is why starboard is tied to the rules of the road at sea. Local regulations vary, so learn the rules that apply to your waters.
The word’s history
The term comes from Old English “steorbord”, meaning the side on which the steering oar was held. Early boats were steered with a paddle on the right side, since most people were right-handed. That is also why boats docked on the other side, or “port” side, to keep the paddle out of the way.
Other directions on a boat
- Bow: the front.
- Stern: the back.
- Forward and aft: toward the bow and stern.
- Abeam: directly to the side.
Learning these few terms makes any time on the water safer and clearer.
Practice makes it automatic
The easiest way to learn is to use the words daily. Label port and starboard on a small model, or call out directions on your next boat trip. Within a few outings the terms become second nature.
