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. 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 (492.1–656.2 ft) in length, though certain bulk terminal restrictions, such as those in Japan, mean that many handymax ships are just under 190 metres (623 ft) in overall length. Modern handymax and supramax designs are typically 52,000- in size, have five cargo holds, and four cranes of 30 t (33.1 ST; 29.5 LT) lifting capacity.

terms for a bulk carrier
Bulk carrier
A bulk carrier, bulk freighter, or bulker is a merchant ship specially designed to transport unpackaged bulk cargo, such as grains, coal, ore, and cement in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have fueled the development of these ships,...

Chinamax
Chinamax is a standard of shipmeasurements, that allow conforming ships to use multiple harbours at maximum capacity. Inversely, harbours and other infrastructure that are "Chinamax-compatible" can receive such ships economically, i.e...

Suezmax is a naval architecture term for the largest ship measurements capable of transiting the Suez Canal, and is almost exclusively used in reference to tankers. Since the canal has no locks, the only serious limiting factors are draft , and height due to the Suez Canal Bridge...
