- Vessels which must transit via the Capes. Either the Cape of Good Hope, which is at the tip of Africa, or Cape Horn, which is at the tip of South America. These ships are considered too big to fit through the canals. Some may be able to transit the Suez, depending on their draft (meaning, how deep of water they require), which varies depending on how much cargo they have onboard.
- Vessels which can fit through the Panama Canal.
- These vessels use to be called Handymax, but for some reason in 2005/2006 the Baltic Exchange changed the term to Supramax (I do not know why). These vessels are smaller than Panamax, but bigger than Handysize.
In collaboration with Hamburg Süd and ZIM, Grand Alliance members Hapag-Lloyd, NYK and OOCL have decided to upgrade their tonnage deployed in the Transatlantic Service between Europe and North America East Coast. From March 2012 instead of four 3,700 TEU vessels, four 5,400 TEU ships are then to come into operation. As hitherto, Hamburg Süd and ZIM will each provide one vessel and Grand Alliance two. The weekly fixed-day service continues to have the port rotation: Rotterdam – Hamburg – Le Havre – Southampton – New York – Norfolk – Charleston – Rotterdam
