AIS Fleet shows the latest reported positions of ships and boats, and sends notices when it detects a vessel you follow departing or arriving. You can watch a favourite ferry, follow a cruise ship, or explore the traffic around a harbour.

You do not need a boat of your own, and there is nothing to install. Sign in at aisfleet.com with your e-mail address, search for the vessel by name, and press Follow. Following five vessels is free, and the free plan does not expire.

Watch your first vessel in about a minute

  1. Go to aisfleet.com and type your e-mail address.
  2. A six-digit code arrives by e-mail. Type it in. There is no password to choose or remember.
  3. Search for a vessel by name, and open her.
  4. Press Follow.

She joins your map and Favorites list, with departure and arrival notices enabled. Notices depend on the reports we receive, so they can be delayed or missed where coverage is limited. Follow your first vessel walks through the steps and helps if the code or vessel does not appear.

Get the app

There is also an iPhone app in open beta. Use the same account to watch vessels on your phone. AIS Fleet on your phone covers installation, notifications and the features that still use the website.

What you get

The guide explains the marine terms as you meet them. The map shows the vessels reported to our network; coverage varies by location.

Who uses it

You can return to this guide from User guide on the sign-in screen or in the account menu.

What it is not

The map is not a complete picture of the sea. AIS Fleet draws the vessels reported to its network, and radio does not reach everywhere. Where the positions come from explains coverage and how to read the age of a position.

There is no ETA, no arrivals board, and no alert when a vessel comes within a distance of you. Following a vessel is what turns her into a notification.

What it costs

Following five vessels is free, on a plan that is not a trial and does not expire. The map, the search, the departures and arrivals, the photos, the messages and your own AIS receiver work the same on it as on any plan. Paid plans follow more vessels, keep more lists, and draw a longer track behind each boat. Plans and billing has the table.

Account settings and deletion

Your account and privacy explains your display name, who can see your activity and how to close your account. If you subscribed through Apple, cancel that subscription in your Apple account before deleting your AIS Fleet account.

Who makes it

AIS Fleet is made by the team behind Saillogger, the automatic logbook boaters use for their own voyages. Separate site, separate account, and you need no Saillogger account to use anything here.

That connection shows up in one place: a few of the boats on the chart keep their logbook with Saillogger, and when their owner chooses to share it, her panel carries more than AIS broadcasts. Boats that log with Saillogger covers what and why. Everything else works whether or not you have ever heard of Saillogger.
