Boat Beacon is the only Marine AIS ship tracking app that provides Collision Detection, use real-time data and can share your own boat’s position with other internet AIS users.

As well as showing all the Ships around you on a chart, Boat Beacon provides Bearing, Range and Closest Point of Approach (CPA) calculations in addition to AIS ship information. Continuously monitors CPA, notifying if potential collisions are detected and transmits to other AIS systems even when the app is in the background.

Key Features

Provides Bearing and Distance information to other boats in addition to AIS information like speed, course, location, name, length etc. Shows you a track of the boats most recent voyage.

Share your live position, speed course and destination. People can follow you using Boat Beacon or our free Boat Watch app and on leading internet AIS systems like MarineTraffic and Ship Finder. Transmit also works continuously in the background when enabled.

Live Map view with compass overlay which rotates with you so you can look in the direction of the ships on the map to locate them. You can also tilt the map to get a 3D perspective by dragging upwards with two fingers.

NOAA US and UKHO Marine Charts (IAP required)

Boat Beacon requires internet access to work. Most popular coastal areas around the world including the US and UK have mobile data access (2G or better) extending 12 or more miles out to sea.

Requirements:
Android Smartphone or Tablet with GPS.
Internet connection.

You do not need an MMSI to use Boat Beacon and you can be seen on Boat Beacon by other Boat Beacon users without having one. However if you want to be seen on Global AIS systems like Marine Traffic, Ship Finder and AIS Hub, etc. then you will need to have and use an MMSI number. If you don't have an MMSI for your boat you can obtain one in the US by visiting http://www.boatus.com/mmsi (the USCG approved agent). Alternatively email us for a free internet MMSI number.

Please note that continued use of GPS running in the background can dramatically decrease battery life.

AIS Ship data is provided by a network of voluntary AIS shore based stations. Some areas may not have AIS coverage.

N.B. This is not an AIS transponder. You will not be visible to other ships on their AIS systems unless they also use data from the same land based AIS networks.

NOT FOR NAVIGATION
This program is distributed in the hope that it will be useful. Boat Beacon should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.

Hi, Boat Beacon has standard apple maps which cover the Black Sea. For marine charts please take look at Boat Beacon's sister app - SeaNav, https://bit.ly/seanav

Ive used this app since i started sharing to Steve's site . The app is my daily driver and have my ais-catcher decoder linked to it as well through various receivers .The app is decent for its simplicity and the ability to share from/to multiple devices is excellent. Also the maps and ship icons are laid out clearly and you can differentiate between them . I see some negative reviews with regards to navigation remember these apps are more hobbyist than accuracy. Keep up the good work . Rab

App is cool, functionally of it sucks, many areas you can be right next to a ship or vessel you know has ais and it literally doesn't even show up on the map. You pay money for the app and all the add ons and then later their customer service basically tells you that they don't have coverage in your area. You should probably tell people that before they pay for the app. Don't waste your money on this app... This app is far more novelty than functional.

Our coastal real-time AIS coverage is amongst the best in the industry. Your particular case was a river which are notoriously difficult to provide AIS for apart from around major towns/cities or by satellite AIS which is not real-time. Folks can check our coverage for free with our BoatWatch app or via our website.
