You can view a vessel's history (including its tracks) back to May 2020—this can be useful for vessels that have not returned to port for a long period of time.
The track history summary provides an overview of a vessel’s movements and the ability to examine its activities more closely.
Zooming in allows you to analyse the vessel’s track further and vessel events can be identified on the track.
Analysing transshipment activity
Starboard automatically detects transshipments at sea by analysing fish carriers and fishing vessels. Likely transshipments and inferred transshipments in Starboard represent potential catch transfer between fishing vessels to fish carriers.
By inspecting potential transshipments in Starboard, you can better investigate potential cases of IUU fishing and human rights abuse as well as better monitor the supply chain of fish products to ensure their traceability and sustainability.
Fish carriers generally report on AIS because they are large enough to be required to carry an AIS transponder (i.e. above 300 tonnes on an international voyage or 500 tonnes regardless of their course).
Try it out: The HUAXIANG8 is over 130 metres and on this 81 day journey has over 65 likely transshipments with 38 vessels, nearly all of which have occurred just outside the Peruvian EEZ in the high seas.
In some cases, fishing vessels are not required to report on AIS because they do not meet the minimum size threshold. If a fish carrier encounters a fishing vessel that is not reporting on AIS this may appear as a loitering event or inferred transshipment.
Analysing fishing activity
The fishing classifier model is applied to the track of every vessel with an AIS vessel class of fishing or unknown. Portions of the track where the activity is determined by the model to be fishing, are coloured pink. Start and stop times for each continuous fishing event are listed in the track history of fishing vessels.
