Your boat can appear on AIS Fleet when an AIS receiver reports her broadcasts to our network, without you creating an account. Some Saillogger owners also choose to share positions directly over the internet.

This page explains what other members can see, what her public page shows to everyone, what you control and how to ask for help with privacy concerns.

What other members can see

Anyone signed in to AIS Fleet, on the free plan, can see of your boat:

• Her name, MMSI, type, flag, call sign and IMO number, and her length, beam and draught, as she broadcasts them.
• Her destination, ETA and navigational status, as they are set on board.
• Her position, speed and course as last heard, and when that was.
• Where she has been, from the reports available to AIS Fleet: the last 24 hours on the free plan, and up to the last 7 or 30 days on a paid one.
• The ports she has visited, based on those reports: the port she is in now, plus her latest port call on the free plan and up to her latest 3 or 10 on a paid one, with the days and times she arrived and left. Port calls
• Photographs other people have taken of her, if any member has contributed one. If somebody photographs your boat
• That she is in a fleet, to the members of that fleet.

They cannot see who owns her, your name, your e-mail address, or anything you have not broadcast, unless you have chosen to publish it (below).

Following her is one-way and does not require approval. If she is claimed on AIS Fleet, you can receive a notice when somebody follows her or adds her to a list, showing their display name. Choose the channels under New followers in Notification settings.

Her public page

A boat on AIS Fleet may also have a page anyone can open without signing in, at aisfleet.com/vessels/ followed by her MMSI, and search engines may list it. Not every boat has one. The page shows:

• Her name, MMSI, type and flag, and the hull details she broadcasts.
• Where she was last heard, and when, as a mark on a satellite map that anyone can move and zoom, with the nearest port or the sea she was in, and her speed when it is available in a recent report.
• While she is under way, her course and her recent track. The mark becomes an arrow pointing along her course, with a line running up to it that shows where she went in the six hours before her latest report, fading toward its older end. Very short tracks are omitted, as are tracks with too few recorded positions to draw on the member map; Track history still opens her reports there. If no course is available, she keeps a round mark and her speed can still be shown. For Saillogger boats, an older speed or course reading may be omitted until she reports it again. If your boat keeps her log with Saillogger, the positions Saillogger sends for her are part of that line only while her AIS Fleet switch, under Settings > Integrations on saillogger.com, is on.
• Her last port call, with one day: the day she left that port, the day she was last heard there if nobody saw her leave, or the day she arrived if no departure is recorded. While she is in port and still being heard, it is the port she visited before the one she is in.
• Photographs members have contributed, once reviewed, and your own photo of the boat if your Saillogger pages are public.
• A short description of her, on some vessels: what is publicly known about her, such as when and where she was built or the work she does. If it was written with AI assistance, a note under it says so. It never says who owns her. A boat claimed on AIS Fleet, or one that keeps her log with Saillogger, has no description.
• Lists that hold her, shared by members or by AIS Fleet, when their creators chose to show them there: each list's name, some of its boats, and its creator's boat, "an AIS Fleet member" or "AIS Fleet".

It does not show her other port calls or anything about her owner, and it names no follower of hers except a list's creator, by their boat's name. Destination and ETA, her track before those six hours, and her port calls, as many as each member's plan shows, are available to signed-in members. Port calls

Choose Track history on her public page, or the link on the map there when it shows her track, to open her last 24 hours of reports on the member map, or one of her photographs to see it full screen with the rest of her photos, signing in if needed. The button under her last port call opens her port calls on her panel, also after signing in if needed.

• To keep her page out of search engines, write to [email protected] with her MMSI. The page stays open to anyone who has its address.
• For a privacy or safety concern, choose Report a privacy or safety concern near the end of her page, or write to [email protected] with her MMSI. If you add an e-mail address to the report, we can write to you about it. We can take the page down, together with her description and her photo gallery on saillogger.com.
• To keep lists off her page, once you have claimed your boat, turn off Show lists on the public page at the end of her panel on the website. In the app, the switch at the end of her panel does the same, and its label includes her name. Her name then also leaves the lists shown on other boats' pages. Members still see those lists on her panel, where her details continue to update. The switch also covers lists you created or subscribed to. You can also write to the same address with her MMSI.
• If something on her page is wrong, such as her description, a photo or a list, choose Report a problem with this page at the end of her About section, or at the end of her photos when she has no About section, and say what the report is about. Reports about her description include the words you were reading. Reports go to the AIS Fleet team, and any changes to her page are made only after the team has reviewed the report. The team can then correct or remove what is wrong. Once you have claimed your boat, her description no longer shows.

After sending a report, choose Send another report if you need to report a separate problem.

The first two do not change what signed-in members see of her AIS broadcast, though taking her page down also removes her description from her panel. Links to the first three are near the end of her page. The link to the third appears only while her page shows lists.

What you control

These are two different things, handled differently.

What she broadcasts over the air is not ours to switch off. Your transponder transmits to every receiver in range, and every AIS site and their customers carry it. There is no button on any website that stops that. AIS equipment has a safety role and may be required aboard your vessel, so whether and when the transponder transmits is decided aboard. If something about how your boat appears here worries you, write to us and we will look at it with you, though we cannot reach copies other services already hold.

What travels with that position is yours to decide, if you keep a logbook with Saillogger:

All of it is re-checked every time somebody looks, not fixed on the day they followed you: turn something off and it is off for everyone from that moment, including people already following. The switches are documented in Share your journey in the Saillogger guide, which is where a Saillogger boater's own settings live.

If you do not use Saillogger, those integration and sharing switches do not apply. You can still manage followers once your boat is claimed, block unwanted messages and contact us about vessel data or photographs that concern you.

Your boat's data can be licensed

AIS Fleet licenses vessel data to other software, including recent positions, AIS tracks, recent port calls and the vessels heard in an area on a past day. Saillogger LLC licenses vessel photos to another company or person only under a written agreement that expressly authorizes their use or display of those photos.

Where such an answer would be built from a position Saillogger sent on your behalf, the AIS Fleet switch under Settings > Integrations decides it, and switching it off keeps your own reports out of what we sell. Where it is built from what a receiver heard over the air, it is the same public broadcast every AIS site carries, and no switch here changes that.

It never includes your journal, your logged track, your messages or anything about your account.

Who follows your boat

Once your boat is claimed here, her followers are listed in your account under Followers, in the account menu.

• Each new one reaches you in Notifications and by e-mail, offering to Follow back where that member can be reached.
• A member who adds her to one of their lists reaches you the same way, and the notice says it was a list, naming it.
• Someone who subscribes to a list your boat is on is not a follower: they are not listed, you are not told, they cannot message you through it, and they see only her AIS position.
• You can remove a follower. Your boat leaves their following list and they are not told, though anyone can follow an AIS-broadcasting boat again later.

If your boat keeps her log with Saillogger, her followers list lives on Saillogger instead, at saillogger.com/app/followers, and AIS Fleet followers appear there with an AIS Fleet badge. That list is not the whole picture, though: it shows the people who can open your pages right now, so it is empty while Live tracking & monitoring is off, and an AIS Fleet follower who does not hold your current access password drops off it while still following your AIS position.

Being watched when you would rather not be

The map reports vessel movements, but cannot establish whether anyone is aboard. That limitation does not remove the privacy concerns a visible position can raise.

• A boat laid up for the winter. Her transponder is usually off, so she is not reporting; what is on the chart is her last position, ageing. Anyone reading her panel sees how old it is.
• Anchored alone somewhere. A follower can see where you anchored and when you got there. They cannot see whether anybody is aboard, and a stale marker is not evidence of anything: it looks the same whether you are asleep below, ashore for a week, or have your instruments off.
• Sailing shorthanded. The same applies. AIS says a hull is somewhere; it says nothing about who is aboard.

If attention is unwanted, or you have a privacy or safety concern, write to [email protected] with your boat's MMSI and the activity involved. We can review it with you. Messages explains how to block contact in the meantime.

If somebody photographs your boat

Members may contribute photographs of your boat, so her gallery can contain pictures you did not take. Every submission is reviewed before it appears.

If a published photo of your boat shows something you would rather it did not show, choose Report a problem with this page on her page and pick A photo, or write to [email protected] with her MMSI, and we will take the photo down. Vessel photos

Claiming her, fleets and messages

Claim your boat is what links her to your account here: her followers listed for you, members able to write to you under her name, notices when a boat you watch comes near her, and nobody else able to claim her afterwards. It is free, and it does not create new position reports or hide existing ones. Her description, if she has one, no longer shows.

Fleets

A fleet is a group of boats on one map with a chat of its own, and you are in one when its organizer adds your MMSI. Everyone in a fleet sees everyone else, which is what separates it from a list, where one member is sorting the boats they watch and your boat joins no group. Once she is claimed, you are told the moment somebody adds her to a fleet, and you can leave in one tap. Fleets covers it in full, from both sides.

Run a fleet

A paid plan lets you start and organize fleets of your own, and you do not need a boat linked to run one, so a club secretary or a rally organizer ashore can run a fleet from the desk. Run a fleet covers starting one, adding boats and what happens if your plan changes.

Messages

Members who follow your boat, and your fleet mates, can write to you, under your boat's name rather than your own. Nobody sees your e-mail address, and you can block anyone. Messages

If your boat already logs with Saillogger

She is on AIS Fleet already, through her MMSI and your sharing settings, so there is nothing to claim and no plan to buy. An ordinary claim cannot be made for an MMSI that belongs to an active Saillogger boat, which is what stops anyone claiming your boat by entering her MMSI.

A claim here is for two people on one boat: a partner or a crew member who wants the boat in their own AIS Fleet account. Claim your boat sets out what that moves, because it changes more than it may appear to.
