Hopefully, a man overboard situation is never a part of your time at sea. But since you can never be too prepared, systems like this can be the difference between life and death. The 1st Mate Marine Safety System uses wearable fobs for the captain and up to seven passengers. The wearables connect to a mobile device and ensure that if the captain goes overboard, the ship will stop and alarms will sound as well as alerts sent to mobile devices. If a passenger goes overboard the captain is alerted with their GPS location to begin the rescue process. Single engine kits are available now.
