The Rescue Solution

The ALERT Man-Overboard Alarm System™ is a marine safety system designed to immediately notify the vessel if someone falls overboard. For a vessel moving 6 knots, a person who has fallen overboard will drift 100 feet in 10 seconds, making the greatest chance of a successful fall-overboard rescue from the vessel that the person fell off.

Compact and easily carried on a Personal Flotation Device (PFD), the ALERT Man-Overboard Alarm System immediately sets off a piercing audible alarm in the wheelhouse upon immersion in water, and can even be wired to stop an engine and/or set a waypoint on a chartplotter.

The automatic water-activated ALERT Transmitter easily attaches to a Personal Flotation Device. It is extremely light and small, making it easy to set it and forget it. There are no antennas or additional strings to get in the way of everyday activity.

Durable

All ALERT products are manufactured to exact industrial specifications and made with high quality materials in the USA. The ALERT2 is Intrinsically Safe Certified which requires that it meets this standard in product strength and structural integrity.

Proven

The ALERT Man-Overboard Alarm System has been protecting mariners since 1996. Hundreds of ships and locations installed and thousands of crew protected from military, government and commercial vessels to the singlehander.

We tested the unit by going the furthest away that we could and getting behind a barge. That test was successful. One of our guys decided to do a real life test this morning, and the Alert2 worked perfectly. Read More

Alerts in Seconds

When every second counts, the ALERT system instantaneously alarms the vessel, providing the crew the critical extra seconds needed for a successful man overboard rescue. Unlike AIS, the response of the ALERT System is immediate. There is no lag time connecting with satellites.

Wired for Engine Kill

For Singlehanders and Solo Fisherman, the ALERT System can be wired to the boat engine to shut down in the event of a fall overboard, giving the man-overboard the opportunity to get back to the vessel.

Automatically Activated

The lightweight water-activated Transmitter easily attaches to a PFD. Upon immersion, the Transmitter instantly alerts the crew of a man-overboard. The proprietary 418Mhz frequency allows it to be automatically activated so it doesn’t have to rely on additional equipment to be triggered.

Plots Overboard Waypoint

The ALERT Receiver can be connected to a compatible GPS plotter to instantly mark the location of the fall overboard. Making it easier to home in the person that fell overboard.

Who Is Protected with ALERT Products?

Tow, Tug, and Barge

The ALERT Man-Overboard Alarm System protects crewmembers who ply the swift coastal and inland waters. “Wearing the ALERT2 gives me a real sense of security” has been echoed by employees of major towboat companies. As a member of the American Waterways Operators organization, Emerald Marine Products understands the dangerous yet vital activities of people working the Tow and Tug Industry and design our products to function in these demanding environments.

Singlehander and Blue Water Voyager

The ALERT Man-Overboard Alarm System was originally invented to serve the singlehander and blue water voyager. When sailing or motoring alone or with a small crew, it's imperative that in the event of a fall-overboard the engine can stop, or at a minimum alert someone to the fall-overboard. It's the precious seconds upon immersion that is the life-saving difference between the ALERT System and AIS or range dynamic systems.

Dredging, Marine Construction and Marine Terminals

Maybe your employees aren't on boats, but they work dangerously close to water. Water that could sweep them out of sight or in cold weather, restrict their muscles within minutes. The ALERT Man-Overboard Alarm System protects employees working near water on dredging, marine construction, or terminal operations. The ALERT Receiver can be mounted in the office or wired to communicate via an auto-dialer of HF Radio to alert of a fall-overboard situation to rescue operations.

Research Vessels

Though a ship has its safety procedures, sometimes people on vessels are not as savvy about working near water as experienced crew. The ALERT Man-Overboard Alarm System is easily worn by visitors or scientists when onboard research vessels. In the event that a person loses their balance and falls overboard, the ALERT System instantly notifies the vessel for the ability to quickly rescue.

Commercial Fishermen

Lore and TV Shows showcase the danger involved in making a living as a commercial fisherman. The ALERT Man-Overboard Alarm System protects crews and solo fisherman by wearing the lightweight and durable Transmitter. This device is automatically activated in the event of a fall-overboard and its Spray-Tight Pouch will protect from false alarms when working in wet conditions. Simple mistakes can instantly take a person over the side of a boat, the ALERT System will immediately notify the vessel.

Military and Law Enforcement Vessels

Law enforcement officials operate in high stake and fast acting environments on the water. It is critical to protect these officials so that they feel confident moving quickly onboard. The ALERT Man-Overboard Alarm System is easy to setup and seamlessly attach to any PFD. The Alert System provides extra confidence and security making it possible for law enforcement officials to focus on the task at hand.
