Live Marine AIS Navigation on your iPhone, Apple Watch and Android Smartphone.
Boat Beacon was designed and developed by Pocket Mariner’s sea-faring CEO after a near miss at sea – the app provides an affordable and reliable AIS-based collision detection system for iPhone and iPad or Android smartphones and tablets. For the full background to Boat Beacon, read The Skipper’s Story – How Boat Beacon Came to Be
Boat Beacon is available now in the App Store for iPhone and iPad and in the Google Play Store for Android phones and tablets. We’re excited to offer exclusive support for the Apple Watch too – Boat Beacon now includes free extra functionality including AIS collision detection, man overboard alerts and navigation tools that run directly on the Apple Watch.
Specifically designed for use on the water, uniquely providing Bearing, Range and Closest Point of Approach (CPA) calculations in addition to all the standard AIS information. Uses up to the second AIS feeds unlike the other AIS apps which can be a minute or even more behind real time. Transmits as well as receives AIS and the only app that continuously monitors CPA, notifying if potential collisions are detected even when the app is in the background.

Other uses for Boat Beacon
We love hearing how our customers are using Boat Beacon – here are just a few examples of stories that we’ve heard…
- Arm all the crews in a race with Boat Beacon and watch real time updates on their positions
- Keep a watch on the other boats in your flotilla when sailing in a group.
- Check your boat is where you left it!
To be seen on Internet AIS systems you must have a valid MMSI number for your boat. You can normally get an MMSI number for free. In the US you can obtain a free MMSI in minutes by visiting the USCG approved agent and using their online form. In the UK visit Ofcom MMSI
Boat Beacon relies on a network of shore based AIS stations for the live ship data. Our coverage is global and amongst the best in the industry, typically showing 40,000 or more live ship movements at any one time and a database of over 150,000 ships world wide. Our coverage is continuously increasing and if you would like to help by adding coverage for your area please let us know. For good locations we will provide the equipment for free. There is more info about how to do this here - Cover your area.
