Built Specifically For These Challenging Times

People are filled with uncertainty and worry, falling overboard doesn’t have to be one of those worries. Ideal for inland and coastal waters, the self-contained system is comprised of an ALERT2 Receiver and two (2) ALERT418 compact water-activated transmitters worn on a work vest. If the deckhand falls into the water, it triggers the ALERT Receiver, which sounds a piercing alarm. It can also be wired to stop engines, set a Chartplotter waypoint, and/or into a ship-wide notification system.

Realizing that the MOB awareness need is greater than ever, and the concern of having third parties on-premise to install any electronic solution, Emerald Marine Products has packaged its ALERT Overboard System to be easily implemented in almost any location. Simply plug the unit into a 110volt outlet or wire to a 12volt system and you are ready to protect your employees. No need for extensive installation, outside contractors, or complicated programming. Watch the video to see how the unit performed on a tugboat when testing out the ALERT system. You can view a video of the unit on board a tug. Click Here.

Now is the time to protect your workers. Don’t let the concerns of COVID-19 stop you from protecting your employees from a fall-overboard fatality. We know that MOBs occur regardless of viruses. As the weather warms up and workers work harder than ever, protecting your employees provides them the confidence they need to do a job well.
