Handymax and Supramax are naval architecture terms for a bulk carrier, in a series that is called Handysize class. Handysize class consists of Supramax (50,000 to 60,000 DWT), Handymax (40,000 to 50,000 DWT), and Handy (<40,000 DWT). The ships are used for less voluminous cargos, even allowing for combining different cargos in different holds.[1][2] Larger capacities for dry bulk are called Very Large Ore Carrier (VLOC), or Chinamax.
The architecture is not defined for maximum route (as Panamax and Suezmax is), but the term is used in shipping capacity markets. These smaller ships usually have self-loading capacity.
A handymax ship is typically 150–200 m (492–656 ft) in length, though certain bulk terminal restrictions, such as those in Japan, mean that many handymax ships are just under 190 meters (623 ft) in overall length. Modern handymax and supramax designs are typically 52,000-58,000 DWT in size, have five cargo holds, and four cranes of 30 tonnes (33.1 short tons; 29.5 long tons) lifting capacity.[2]
