Baltimax is a naval architecture term for the largest ship measurements capable of entering and leaving the Baltic Sea in a laden condition.

The limit is a draft of 15.4 metres and an air draft of 65 metres (limited by the clearance of the east bridge of the Great Belt Fixed Link).

Nevertheless, there are also certain larger ship types plying the Baltic Sea.

Particularly the so-called B-Max crude oil tanker with more than 205,000 tons deadweight (68 m width, 325 m length)[1] and the Maersk Triple E class container ship, 400 m length and 165,000 metric tons deadweight.

The largest port is Primorsk which has 15 m draft, similar to Baltimax.
