Mooring Alarm keeps watch on your anchored boat's GPS position and alerts you immediately if the vessel drifts beyond a set safe zone. Mooring Alarm triggers a local alarm and can send an SMS to a chosen phone number. Mooring Alarm is built for boat owners and cruisers who want passive, reliable protection while ashore.
