In order to start creating your first fleet, click on the "Create one" link or directly click on the "Vessels" tab.
Let's suppose you wanted to create a small fleet of, say, container vessels.
First of all, you should find the vessels that you wish to be included in this fleet. This can be done by typing the Name (or the MMSI or the IMO) of the subject vessel in the related field. Notice that while you are typing, a list of vessels with similar names will appear - select the one you are looking for and click on the adjacent "Add to new Fleet" button.
A pop-up window will appear asking you to name your newly-created fleet. Name it as you please and click on the "Create Fleet" button (note that if you have enabled "Fleet Colours", you will also have to define a colour for your fleet).
Since this is your first-ever created Fleet, it will also be your default one. In order to add more vessels to this fleet, all you have to do is to repeat the same process.
Notice that this time, the "Add to new Fleet" button has been replaced by the "Add to default fleet" one. Obviously, there is no need for you to provide MarineTraffic with the name of your fleet again. Repeat this process to add as many vessels as you please to this fleet (keep in mind the maximum size of it depends on the subscription plan of your choice and on any Fleet Extension Add-ons you may have purchased).
The vessels that you have added to your fleet will be listed below
Tip: If you know the MMSI or the IMO of the vessels you wish to be included in your fleet, you can use the "Import vessels to your fleet option" and import them all at once.
Simply, type the respective numbers of the subject vessels. You can either type these numbers comma-separated on the same line or use one line per number (as in the example in the following picture).
Choose the initial status of these vessels (OFF/ON/SAT) and click on the "Import vessels to your fleet" to complete this process!
