Digital Yacht’s MOB Alert has a button that creates and shares a synthetic AIS (automatic identification system) search and rescue transponder PGN (parameter group number) and an NMEA 2000 MOB PGN with the vessel’s N2K network. Networked multifunction displays instantly detect these PGNs and show them onscreen, like signals from an AIS beacon. MOB Alert captures the boat’s GPS location when the button is pressed, not the MOB’s real-time position, but this helps the captain navigate to the MOB.
While MFDs usually have MOB buttons, Nick Heyes, Digital Yacht’s CEO, says they are “often buried in a menu or require an odd key sequence to activate, and the [display] may be belowdecks.” This solution creates a dedicated button that yields two kinds of PGNs for maximum compatibility, he says, making MOB Alert a simple solution to mark an MOB’s position on just about every modern display.
Easy Installation
Digital Yacht suggests installing the MOB Alert’s control box close to the yacht’s N2K backbone. Multiple MOB Alert panels can be wired in parallel to a single control box, reducing the distance traveled to activate the system. Alternatively, MOB Alert systems can be activated by an outboard-style kill cord switch. An optional Digital Yacht NavAlarm NMEA 2000 sounder yields a 102-decibel alert.
