When you are in the map view press the vessel button. Choose Lists from the pop-up screen. Click Create new to start the search for vessels. Enter name for your new list.
When you have named your new list you can start adding vessels. You can either search by them individually by entering the name, or part of a name, of a vessel in the search field, or by clicking the green funnel symbol to the right to choose between various filters.
You can add several filters by pressing save after each choice.
When you have chosen your filters, you add vessel to your list by clicking on them. When your list is complete you click done. You will then see the list you have just made. If you find that you need to make any changes to your list, you can edit or add vessels, add team notes, or delete the list to start over. Or if you want to view your list in the map, click find in map. You also have the same choices directly from your overview of your lists.
