First, you must be logged into your Global Fishing Watch account. The custom fleet feature lets you select and group a set of pinned vessels with the objective of seeing them moving as a fleet in the map (with the same color).
- Search or select the vessels you are interested in being grouped in a fleet.
- In the right menu go to Vessels, you should see all pinned vessels.
- Click the `Create Fleet` button.
- Click on the checkboxes of all vessels you want to include in the fleet.
- Customize the fleet name and color.
In case you want to remove the fleet you have created, click on the fleet edit button and then `Break Apart Fleet.`
