Full Container Ship
These are also called cellular vessels and are purpose-built to carry containers.
Container ships are commonly categorised by their TEU (Twenty Foot Equivalent Units) capacity. Those with capacity up to 3,000 TEUs are of the Panamax size with beams suitable for passage through the Panama canal.
Those with capacities exceeding 3,000 TEUs come under the post Panamax category and are commonly termed the "fourth generations" and above.
