1st Mate

Marine Safety & Security System

1st Mate® is a convenient wireless system that utilises wearable fobs and a mobile app to provide overboard alerts, distress messaging and theft-deterrent functionality.

Confidence at hand

Overboard monitoring

If the captain falls overboard, the engine(s) will stop, an alarm will sound and alerts with instructions for returning to the location of the incident will be sent to connected passengers via mobile app. If a passenger falls overboard, the captain will be alerted and given the location via the app.

Engine cutoff functionality

For the captain, 1st Mate is a safe, convenient alternative to the traditional mechanical emergency stop switch and lanyard that can be worn anywhere in the boat.

Distress messaging

In the event the captain goes overboard, 1st Mate can send a distress message with location, heading and time to emergency contact(s) once a pre-set countdown timer expires or a request for help is made.

Theft Deterrent System (TDS)

TDS can lock your engine(s) to prevent unauthorised use. Once you are ready to get behind the wheel, your engine(s) can easily be unlocked via the proximity of the captain’s fob or by using the 1st Mate app.


The 1st Mate system can connect the captain and up to seven passengers. There are versions for Mercury SmartCraft®-compatible engines and for all leading engine brands.
