Abstract: The cargo payload of a merchant vessel is a crucial variable in calculating revenue for a particular voyage and estimating global trade flows for key commodities. However, due to the opaque nature of the industry, payload information is usually not publicly available. This research utilises, for the first time, vessel draught information reported by the automatic identification system (AIS) to estimate vessel payloads. The applicability and reliability of draught measurements from AIS captured via satellites and terrestrial receivers are addressed in the process of identifying the most efficacious way to estimate vessel payloads.
