๐ข Port vs. Starboard: Which Side of a Cruise Ship Is Which?
If you are new to cruising, two nautical terms you will hear frequently are port and starboard.
The simple rule is:
๐ด PORT = LEFT
๐ข STARBOARD = RIGHT
When facing the bow, or front of the ship, port is on your left and starboard is on your right.
Why Not Simply Say Left and Right?
On a moving ship, "left" and "right" can become confusing because they depend on which direction a person is facing.
Port and starboard always identify the same side of the vessel, making communication much clearer during navigation, docking, emergencies and safety operations.
The system is also important when identifying other vessels at sea. Navigation lights use:
๐ด Red = Port
๐ข Green = Starboard
These lights help ships determine another vessel's position and direction, particularly at night or in poor visibility.
โ Where Did the Names Come From?
The terms date back hundreds of years.
Before modern rudders, boats were commonly steered using a large steering oar positioned on the right side. This eventually became known as the steering side, which developed into the word starboard.
The opposite side was once called larboard, associated with the side used for loading cargo.
Because "larboard" sounded too similar to "starboard," the term was eventually replaced with port, referring to the side commonly used when a vessel came alongside a port.
Today, port and starboard are internationally recognized maritime terms.
๐ณ๏ธ Does Your Cabin Side Matter?
Sometimes, yes.
On a round-trip cruise, both sides of the ship usually get different views throughout the journey.
But on a one-way cruise, choosing the right side can make a significant difference.
For example, on a northbound Alaska cruise, a starboard-side cabin may provide better views of the coastline. On a southbound sailing, the port side may offer better views.
The direction of travel also matters if you're hoping for sunrise or sunset views.
๐ช How Do You Know Which Side Your Cabin Is On?
Most cruise ships have PORT and STARBOARD signs near elevators, stairways and corridors.
Some ships also use cabin numbers to indicate the side, with even and odd numbers assigned to different sides. However, this isn't universal, so always check the ship's signage.
Even experienced cruisers can get confused when sailing on a new ship! ๐
๐ Other Nautical Terms You Should Know
Bow / Forward โ front of the ship
Stern / Aft โ rear of the ship
Bridge โ navigation and command area
Beam โ widest part of the ship
Draft โ depth of the ship below the waterline
Keel โ main structure along the bottom of the vessel
Lee side โ side protected from the wind
๐ง The easiest way to remember:
๐ด PORT = LEFT
๐ข STARBOARD = RIGHT
And remember: Port wine is red. ๐ท
So the next time a crew member says, "Meet me on the starboard side, aft," you won't need to stop and ask which way to go! ๐๐ข
