New Garmin OnBoard Wireless Man Overboard detection and engine cutoff system
November 20, 2025
Garmin, the world’s largest1 and most innovative marine electronics manufacturer, has announced Garmin OnBoard™, a versatile Man Overboard (MOB) and engine cutoff solution for boaters that uses wireless technology instead of traditional tethered cords.
Tags can be worn on a wrist band, carabiner or key ring float, and designated as either captain or passenger. If an MOB is detected, the system will save a waypoint on the chartplotter, and audible alarms will sound. Should the captain fall overboard, the system will also automatically trigger engine cutoff. Captains can also disable the engine via a button-press on the tag if needed. With up to 8 MOB tags, mariners can tag what matters most – adults, children, pets and objects – all at the same time.
“Wearing an MOB tag that can activate an engine kill switch on a boat can potentially save lives. As part of our commitment to making boating safer and more enjoyable for everyone, we designed Garmin OnBoard with safety and convenience in mind using wireless, non-intrusive tags that will bring the boat to a stop and alert those on board if an MOB event is detected.”
–Susan Lyman, Garmin Vice President of Consumer Sales and Marketing
