Digital Yacht NavAlert NMEA 2000 Monitor Alarm System

The Digital Yacht NavAlert NMEA 2000 Monitor Alarm System lets a boater set an alarm on any parameter available across the boat's NMEA 2000 network, navigation readings like depth, heading, or speed, or electrical and engine data like voltage, temperature, pressure, tank levels, and fuel flow.

Installation is deliberately simple: it plugs in anywhere on the NMEA 2000 network and draws power straight from that same connection, no separate wiring run required. NavAlert creates its own local Wi-Fi network for setup, so configuring it from a smartphone, tablet, or PC just means picking a parameter to watch and setting the threshold that should trigger an alert.

One built-in feature stands out: a custom anchor drift alarm that calculates an appropriate drift radius based on actual water depth and the scope of chain paid out, giving reliable notifications rather than a generic fixed-radius alert that ignores real anchoring conditions.
