1st Mate Marine Safety and Security System utilises wearable fobs for boat captain and up to seven passengers. These wearables connect to a mobile device and ensure that if the captain falls overboard, the engine(s) will stop, an alarm will sound and alerts will be sent via the 1st Mate mobile app, thanks to direct integration with the vessel’s propulsion system. Similarly, if a passenger falls overboard, the captain will be alerted and given the passenger’s GPS location via the app.
