Baltimax
B5. Ship Types and Individual VesselsDefinition
Largest size able to navigate the Baltic.
Baltimax is the largest ship able to enter and leave the Baltic Sea fully laden, set by the Great Belt route through the Danish Straits. The binding limits are a draft of 15.4 meters and an air draft near 65 meters, the latter fixed by the clearance under the East Bridge of the Great Belt Fixed Link. A Baltimax runs roughly 240 meters in length and 42 meters in beam for about 100,000 dwt. The Oresund allows only about 8 meters of draft and the Kiel Canal about 9.5 meters, so neither serves as an alternative for a deep ship; the Great Belt is the only deep gate.
