Container Ships carry the majority of the world's dry cargo, informally known as "Box Boats". There are large main line vessels that ply the deep sea routes, then many small "feeder" ships that supply the large ships at centralized hub ports. Most Container ships are propelled by
Diesel engines, and have small crews of between 20 and 40 people. They generally have a large accommodation block at the
stern, directly above the
Engine Room[?].
