How it works: Vessel subtypes
How it works: Vessel subtypes

Updated over a year ago

To support efficient fisheries monitoring, control and surveillance (MCS), Starboard augments the AIS-reported vessel type with more granular vessel subtype data obtained from Regional Fisheries Management Organisations (RFMOs).

The AIS vessel type, flag, dimensions, IMO, MMSI, and call sign are all entered manually by the crew onto the AIS transceiver and can be incorrect.

Vessel type does not include detailed information, for example, the specific subtype of a fishing vessel or whether a cargo vessel is used as a fish carrier. RFMOs collect and maintain this more detailed information in order to regulate high seas transshipment and other fishing activities.

Starboard brings in data from RFMO records and matches it to vessels reporting on AIS in the Starboard database. See How it works: Fishing registration data from RFMO records for more information.

Vessel subtypes from RFMOs are then updated in Starboard for corresponding vessels. This information can be found in the vessel details panel and in the vessel report, where available. Vessel subtypes from RFMO records are also available within Starboard’s advanced filtering under ‘Vessel type’.

In the future other vessel information will be integrated in the same way to improve the vessel information.

Current sources of vessel subtypes

In order of priority for when multiple vessel subtypes are available:

Standardisation of vessel subtypes

We use the International Standard Statistical Classification of Fishery Vessels (ISSCFV) by Vessel Types (Rev.1, 2019) of the ​​Food and Agriculture Organization of the United Nations (FAO) to standardise fishing vessel type names across multiple RFMOs.

Vessel details displayed in app are broadly mapped from the FAO Level 1 category, although there are a few exceptions, for example various types of support vessels
