The boat tracker built around the people ashore.

SHORT ANSWER

Looking for a boat tracker in Canada? To see ships and ferries, use an AIS app. To let the people ashore see your own boat, use a live link, and that’s what VesselSOS does. They follow your position, speed, course and battery in an ordinary browser, with no app and no account. Tracking runs only during a trip you start, and the same data fills in the SOS screen if the day turns. It’s a TestFlight beta on iPhone now. The link is part of Pro: CA$3.99 a month or CA$19.99 a year, with a 14-day free trial.

How the live link works

01
Start tracking

Tap Going to sea, pick who sees you and set a return time. Tracking stops when you tap I'm ashore. Nothing runs before or after.

02
Share the link

Your Live contacts get it by text: one tap opens the message, then you hit Send. It opens in a browser, so the person ashore installs nothing and signs up for nothing.

03
They watch you move

Position, speed, course and your phone's battery level, live on a map. You choose how often it updates, from every 5 seconds to every 5 minutes.

A sail plan and a live link do different jobs

Transport Canada asks you to file a sail plan with someone you trust before every trip, with your route and a description of your boat, and to have them contact a Joint Rescue Coordination Centre if you’re late. Keep doing that (how a sail plan works). But a sail plan only says where you meant to go, and someone ashore still has to notice you’re late. A live link helps them notice: they see where you actually are. If you’re past your return time, the app asks you, on your own phone, whether you’re OK. Its automatic texts to your contacts don’t reach Canadian (+1) numbers yet, so it doesn’t text anyone else here. And if the dot stops somewhere it shouldn’t, what to say on the radio is one page away.

How it compares

TRACKERHOW IT WORKSTHE CATCH
AIS apps and transponders An AIS transponder broadcasts your position to other boats and public ship-tracking sites; the “flight radar for boats” apps show those signals You need the hardware to show up at all, and most runabouts, fishing boats and canoes don’t carry it. Great for spotting ships, not for family watching your boat
A paper or emailed sail plan Route, boat, people on board and return time, left with someone you trust (Transport Canada has a form you can print or email) Says where you planned to go, not where you are; nobody is alerted unless that person acts
Chart-app track Records your route on your own phone Usually stays on your phone: more logbook than a way to be seen
VesselSOS link Live position, speed, course and battery in a browser link for the people you choose Needs your phone and cell coverage; positions logged without signal are sent when it returns. Offshore and in the North, carry an EPIRB or PLB regardless
VesselSOS friends Friends you accept see your live position, speed, course and battery during a trip, and get a push notification when you head out and come back Pro; only during a trip with “Show friends when I’m at sea” on. Friends get no overdue alert, and automatic overdue texts to your contacts don’t reach Canadian numbers yet

Battery and privacy

Outside a trip the app doesn’t track you at all. During a trip it reports in the background, every 30 seconds by default (roughly 4% battery an hour by our estimate), and below 20% battery it slows to every 5 minutes on its own. The people watching see your battery level, so a dead phone never reads as a drifting boat. Trip history is kept for 12 months, then deleted automatically. And this website sets no tracking cookies unless you allow them.

HONESTY CLAUSE

A tracking link is not a distress system. It tells your people where you are; it doesn’t alert anyone. In a life-threatening emergency, make a Mayday on VHF channel 16 if you have a radio, and call the Coast Guard rescue centre for your waters (911 on inland lakes and rivers). The app’s SOS screen makes that call fast, and offshore you should still carry an EPIRB or PLB.

Frequently asked

Does the person ashore need the app?+

No. The link opens in any browser, on any device, with no account. That’s the point: the least techy person in your family can watch you.

Is this like a flight radar for boats?+

No. Those apps show other vessels’ AIS signals. VesselSOS shares your own position, from your phone, with the people you choose, with no AIS hardware on your boat.

Does it work in a canoe, on a paddleboard or a personal watercraft?+

Yes. Set your boat type in the profile: sailing boat, motor boat, SUP/kayak or jet ski. Its name, type and colour go into the call script, and its name into the texts you send.

What happens if I lose cell coverage?+

The link shows your last known position and that the signal is lost. Positions recorded without signal are queued and sent when coverage returns. Your phone keeps its GPS fix fully offline, so the SOS screen still has your position and Mayday text.
