Navigating a Cruise Ship: How to Not Get Lost

Forward vs. Aft

The four most common terms in ship directional language are forward and aft, and starboard and port. What makes things confusing is that the latter terms refer to sides of the ship, whereas “forward” and “aft” refer to directions. The bow of a ship is located at the front of the ship, and the stern is at the back. When a cruiser walks from the stern to the bow, this is forward, and when walking from the bow to the stern, this is aft. So, in summary, forward is the front, and aft is the back.

These terms matter more practically than you might think. Cabin location descriptions on cruise booking sites use these terms, and knowing them helps you choose a stateroom. Aft cabins (at the back of the ship) can have beautiful wake views, but may experience more vibration from the engines. Forward cabins can have excellent views on upper decks but feel more motion at sea. Mid-ship cabins split the difference and are the smoothest ride for anyone prone to seasickness.

Port vs. Starboard

When looking at the bow of the ship from the stern, the right side of a cruise ship is the starboard side, and the left side of the ship is the port side. Why not just call it “right” and “left”? Well, that goes way back to early nautical times when ships had a steering paddle on the right side (the “steer board” side), and the tradition has stuck across centuries of seamanship.

These terms are consistent on every ship in the world. Port is always the left side, starboard is always the right, regardless of which direction you are facing. If you’re interested in the full history, including how starboard evolved from “larboard,” the NOAA has a quick read on it.

How a Cruise Ship Is Laid Out

Understanding the basic layout of a cruise ship makes everything else easier. Ships are organized by decks, which are numbered floors. Deck 1 or Deck 2 is near the waterline at the bottom; higher deck numbers are progressively higher on the ship. The pool deck, lido deck, and open-air areas are always at or near the top. Main dining rooms are usually on lower or mid decks. The theater is often forward on lower-middle decks. Specialty restaurants, bars, and entertainment are typically spread across mid-ship on multiple decks.

Your cabin deck number is baked right into your cabin number. On most ships, a cabin numbered 6214 is on Deck 6; cabin 10547 is on Deck 10. The remaining digits indicate position along the corridor. Odd-numbered cabins are typically on the port (left) side, even-numbered on the starboard (right), though this varies by cruise line. When in doubt, check your ship’s deck plan.

Every cruise line’s app has the ship’s deck plan built in, and it’s the single most useful tool for new sailors. Download it before you board. On Royal Caribbean ships, the app includes turn-by-turn navigation to venues and restaurants. Carnival and Norwegian have similar functionality. Even if your cruise line’s app is less sophisticated, having the deck plan at your fingertips eliminates most first-day confusion.

Most ships also have a prominent atrium, which is a multi-story open space usually located mid-ship. The atrium is your best landmark for reorienting yourself when you feel turned around. Guest services desks are almost always located in or directly adjacent to the atrium, which is also where you’ll find the main staircase banks and elevator clusters.

Getting Around on Board

When selecting a stateroom during a cruise booking, one might assume that booking a room on the port side is preferable, as this gives visibility to the port area when the ship docks. This, however, is not always the case, and ships regularly dock on both the starboard and port sides, making neither side particularly advantageous for most sailings. The side that faces the port changes at every stop.

On your first day aboard, getting turned around is completely normal. Modern cruise ships can be 18 or more decks tall and over 1,000 feet long. The key is to build a mental map early. On embarkation day, take 20 minutes to walk the public areas on two or three different decks before you do anything else. Find the theater, find the main dining room, find the pool. Once those anchor points are locked in, you can navigate from them.

Hallway signage is your best friend. At the end of every cabin corridor, there are direction signs pointing you toward forward or aft, indicating which cabin numbers are in each direction. Pay attention to these the first few times you walk your deck and you will build orientation quickly. Most people feel reasonably comfortable navigating independently by the second day at sea.

Quick Tips for Getting Your Bearings

• Pick up a printed ship map at the guest services desk on embarkation day, or download the cruise line’s app and navigate to the deck plan before you sail.
• Odd-numbered cabins are typically on the port side and even-numbered cabins on the starboard side on many ships, though this varies by cruise line. Check your ship’s deck plan to confirm.
• Elevator lobbies on most ships are grouped toward the middle of the ship. Finding them is the fastest way to reorient yourself when you feel turned around.
• Look for signage at the end of every corridor indicating deck number and cabin numbers in each direction. These are your best friends on a large ship.
• The atrium (the multi-story open central space, usually mid-ship) is the single most reliable landmark on almost every cruise ship. When lost, find the atrium.
• It typically takes one or two sea days before most passengers feel comfortable navigating independently. Give yourself grace on the first day and use the app freely.
