Improve your experience at sea with OnCourse, the new boating and sailing navigation aid from MarineTraffic, the global leader in vessel tracking.
OnCourse helps you stay aware of the traffic around you, plan your voyages, while sharing your position with your friends and loved ones through the MarineTraffic Live Map.
Increase your awareness while sailing
- Plan and monitor your voyage*
- Calculate the optimal route*
- Add your own customisable waypoints to the map
- Collision detection & avoidance while sailing, with AIS
- Additional information during sailing (time to next waypoint, next ETA, final ETA, distance & bearing to waypoint)
Share your position on MarineTraffic.com and engage with the boaters’ community
- Report your own position even if your boat is not equipped with an AIS transponder, so that your friends and family can follow you in near real-time
- Track a particular boat in a race or keep in touch with friends’ boats whilst cruising
- Identify other vessels that are sailing in the area (provided that they transmit their positions)
- Upload photos of your boat for all the community to see
- Recognise vessels by using the Augmented Reality tool*
- Try out the VR feature (requires a VR headset)*
Very low data and battery consumption
All standard units of measurement supported
(*) Available only with OnCourse Plus subscriptions
Note: OnCourse is not AIS, OnCourse simulates the data transmitted by AIS transponders; however, it only transmits data through the Internet and not over AIS radio-frequencies. The information transmitted by OnCourse is not visible by the AIS receivers of other vessels. It will only be displayed on the MarineTraffic website and apps. As such, OnCourse is a self-reporting tool that does not substitute AIS transmissions and it is not, by any means, related to the safety and navigation equipment of a vessel.
Provided that Internet connectivity is available, the vessel's positions will start being reported once the OnCourse application is launched on your mobile device. Positions will continue being reported even if the app is running in the background! Broadcasting must be turned off whenever the device leaves the vessel.
How to use OnCourse - Registration Required
Registration for a MarineTraffic account is required in order to start reporting your position through the application. The details of the vessel must be also configured when using the app.

Ratings and Reviews
Does not seem to work reliably
The app has apparently replaced the previous mAIS app. In the past I used the mAIS app all the time when out on my boat so that my friends and family could see where we were boating. My brother also used it when we was out and I could track his progress.
This new app does not seem to work. Both my brother and I have been trying to use it over the last few weeks without much success.
We are logged into accounts, we have mmsi numbers registered, we are cruising in areas with decent cell coverage. It just doesn't seem to report our position.
Perhaps if I bought the upgrade to the "pro" version it would work but why would I do that. Based on the description of the app, the free version should simply report position.
Horrible interface print so small on iPhone
The mAIS app use to be so good. Not so much here. Can’t even read the screen to see the prompts on iPhone 11 Pro Max. Wish they would fix this.
