Cruise Glossary

Every term you'll hear on deck — from cabin types to gratuities to tender ports — in plain English.

A

Aft
The rear (stern) of the ship. Aft-facing cabins look back along the wake — a favorite spot for sunset lovers.
All-inclusive
Fare that bundles drinks, gratuities and sometimes excursions or specialty dining into one upfront price. Most mainstream cruises are not all-inclusive by default.
Atrium
The ship's central, multi-deck open foyer — usually the social heart of the vessel, with shops and guest services around it.

B

Balcony cabin
A stateroom with a private outdoor veranda. Often the sweet spot between price and experience for longer sailings.
Berth
Either a ship's allocated spot at a pier, or a bed in a cabin. When a port 'has three berths', three ships can dock at once.
Bow
The front (fore) of the ship.

C

Cabin (stateroom)
Your room on board. Types from cheapest to priciest: interior, ocean view, balcony, suite.
Cabin guarantee (GTY)
A discounted booking where the cruise line assigns your specific cabin later — you pick the category, they pick the room number.
Cruise card
Your all-in-one onboard ID, room key and payment card. You'll use it to board, buy drinks and settle your account.

D

Debarkation
Leaving the ship at the end of the cruise. Also the source of the dreaded final-morning luggage-tag colors.
Disembark / Embark
To exit (disembark) or board (embark) the ship. Embarkation day is the first day of your cruise.

G

Gratuities
Automatic service charges (typically $14–$20 per person per day) shared among cabin stewards, dining staff and crew. Prepaid at booking or added to your onboard account; adjustable at guest services.
Gangway
The movable ramp or staircase between the ship and the pier used to board and go ashore.

I

Inside cabin
A windowless interior stateroom — the most affordable way to sail. Dark and quiet, ideal for travelers who spend their days on deck.
Itinerary
The ship's planned route: ports, arrival times and sea days. 'Port-intensive' itineraries stop almost daily; 'sea-day-heavy' ones favor onboard time.

K

Knot
One nautical mile per hour (1.85 km/h). Cruise ships typically cruise at 18–22 knots.

M

Muster drill
The mandatory safety briefing at the start of every cruise, showing you your lifeboat station and how to don a life jacket. Attendance is required by maritime law.

O

Ocean view cabin
A cabin with a window (or porthole) looking outside, but no private balcony.
Onboard credit (OBC)
Prepaid spending money on your cruise account — often gifted as a booking perk or applied by travel agents.

P

Port of call
A scheduled stop along the itinerary where the ship docks (or anchors) so guests can go ashore.
Port / Starboard
Nautical left (port) and right (starboard) when facing the bow. A handy trick: 'port' and 'left' both have four letters.

R

Repositioning cruise
A one-way sailing that moves a ship between seasonal regions (e.g., Caribbean to Mediterranean). Unusual ports and low prices, but you fly home from a different city.

S

Sea day
A day with no port stop — pure onboard time for pools, spa, entertainment and enrichment talks.
Shore excursion
An organized tour booked through the cruise line (or independent operators) in a port of call.
Starboard
The right side of the ship when facing forward.
Stern
The back of the ship — look for stern-view restaurants and cabaret lounges on modern vessels.
Suite
The top cabin category, with separate living areas, priority services and often butler service.

T

Tender
A smaller boat that ferries guests ashore when the ship anchors offshore rather than docking. Tender ports add extra time to get to land — plan accordingly.
Theme cruise
A sailing built around a shared interest — music, fitness, food and wine — with special programming and like-minded guests.

W

Wave Season
The industry's big booking window (roughly January to March) when cruise lines release their best promotions, drinks packages and onboard credits.
