• draft¹⁾
• the depth of the lowest point of the vessel below the waterline²⁾

The draught is the vertical distance from the waterline to the baseline; a change in the draught generally means a change in the ship’s weight and cargo.¹⁾

According to Lloyd’s List, as draught data is a manual input done aboard a ship it is not always a reliable source of information. However, there are certain instances where draught data must be accurate for safety reasons, such as passing through major chokepoints.²⁾
