Boat Beacon App, for smartphones & tablets now on Android following its success on iPhone; improves safety at sea for boaters. Mariners can now use their Android devices to keep a watch on nearby boats along busy coastlines while enabling other boatsto follow their current location using Boat Beacon Maps and Global Marine AIS systems. The Boat Beacon app, developed by a skipper for other skippers, does not require an external AIS receiver or transponder equipment and provides location tracking at a fraction of the cost of an AIS system.
