Tags as filters

Tags are added to vessels of interest and stored in your organisation's Tagged Vessels menu.

You can use tags as filters to isolate specific fleets of interest for analysis. Use the + Filter menu to select multiple tags from your organisation's list, or use the Quick Filters in the Analysis results panel to select tags of interest based on the vessels present in your current map view.

You can then apply more filters (such as risk indicators or vessel activity) to further highlight noteworthy behaviours or events within the tagged fleets. This is particularly useful for daily monitoring of large global fleets for new activity of interest.

Tip: Many of the filters can also be used as exclusions, by toggling from ‘Any’, to ‘None/not'. For tags, this means you can exclude a list of vessels that you are not interested in seeing in your results.

Analysing tagged vessel activity by area

When analysing fleet behaviours within specific areas of interest, there are two different options for area-based filtering in Starboard.

  • Vessel-based filtering is the default setting when filtering by area. It returns all vessels that exhibited the filtered behaviour(s) within the set timeframe, even if the behaviour occurred outside the selected area—as long as those vessels entered the area at some point during the specified timeframe.

  • Events-based filtering can be enabled from the Vessel activity filter menu, and returns only the vessels with events that occurred inside the selected area during the specified time frame.

Filtering on events within a set area and timeframe is enabled by selecting a Vessel activity filter and ticking the box that says “Only show activity within the set area”. This feature enables analysts to focus on high risk behaviours in very specific areas such as known smuggling routes, ship to ship transfer hotspots, loitering zones, and protected areas.
