Inside a Cargo Ship: A Deck-by-Deck Tour of a Container Ship

Last updated: 26 October 2026 · By Steve Joury, cargo trip advisor at CargoHolidays

Inside a cargo ship, most of the space is cargo hold; the people live and work in a tall accommodation block with cabins, mess rooms, a galley and, at the top, the bridge. Deep below is the engine room. Here’s a deck-by-deck tour of a typical container ship – the kind freighter passengers sail on.

Key facts at a glance

  • À propos de 90% of a container ship’s volume is cargo space.
  • The crew live in an accommodation block (the ‘house’) several decks high.
  • The bridge sits at the top for a clear view over the containers.
  • The engine room is low down near the stern.
  • Passenger cabins are usually in the accommodation block, near the officers.

The cargo holds

Step inside a cargo ship and the first thing you notice is how little of it is for people. The hull is divided into huge holds, each fitted with vertical steel guides (cell guides) that hold containers in stacks. Hatch covers close the holds and more containers stack on top. Read how container ships are loaded to see how it all fits.

The accommodation block, deck by deck

LevelWhat you’ll find
Main deckShip’s office, stores, changing rooms, gangway access
Lower accommodation decksGalley, crew mess and officers’ mess, laundry, gym
Middle decksCrew cabins, recreation room, sometimes a sauna or small pool
Upper decksOfficers’ cabins, passenger cabins, captain’s and chief engineer’s suites
Navigation deckThe bridge, chart area and radio station

On large modern ships the accommodation block may sit further forward rather than right at the stern, which gives the bridge a better view over the stacks.

The bridge

The bridge stretches the full width of the ship, with bridge wings on each side for berthing. Inside you’ll find radar screens, electronic chart displays, the autopilot, radios and the engine controls. One officer and a lookout keep watch around the clock. Passengers are usually welcome to visit when the captain allows. Our guide to how cargo ships navigate explains the equipment.

The engine room

Deep in the stern, the engine room houses the main engine – a slow-speed diesel the size of a building on the largest ships – plus generators, boilers, pumps and the engine control room. It’s hot, loud and fascinating. Ask the chief engineer for a tour with ear protection. Read how big is a cargo ship engine.

Cabins, mess rooms and the galley

Crew cabins are simple and functional; officers’ cabins are larger with a separate desk area. Passenger cabins are often surprisingly spacious, with a private bathroom and windows looking forward or to the side. The galley feeds everyone, and meals are served in the mess rooms.

The forecastle and steering gear

At the bow, the forecastle holds the anchors, windlasses and mooring winches – see how ship anchors work. At the stern, the steering gear room moves the huge rudder. Both are off-limits to passengers unless escorted.

Tip: The best way to see inside a cargo ship is to sail on one. Most passengers get a guided tour of the bridge and engine room during the voyage.
