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.

There are limitations with equipment which precipitate this issue; however, the major concern is with the lack of international laws to prohibit the use of AIS transponders. The IMO needs to take a stand on this issue and prohibit the use of AIS on anything other than a vessel. One solution could be designating AIS symbols for vessels and others for fishing nets, buoys, and other gear such as long lines, hydrographic survey or dredge equipment. This would allow the prudent mariner to differentiate between ships and other floating gear allowing for a reasonable assessment of a close quarters situation.
