Features & Capabilities

Vesper Monitor works with your on board Vesper Marine Cortex M1 device to monitor both the built-in Cortex sensors and other sensors on your boat that you connect to your Cortex Hub.

  • Setup is easy and free
  • Use the Cortex Hub’s built-in sensors for battery level, barometric pressure and boat position.
  • Connect your Cortex Hub to NMEA 2000, or an external sensor, to add monitoring for wind, depth, bilge high water, temperature, shore power or security.
  • Unlock your Cortex Hub to receive real-time sensor information, alerts and remotely control key circuits like air conditioning, lights or refrigeration.
  • Once you’ve unlocked your Cortex Hub you can also track your vessel, set geo-fence alarms and use Vesper Marine’s Award Winning smartAIS AnchorWatch to know your boat is safe at anchor.

User Reviews

User reviews show strong positives for easy installation, remote boat data access, voltage alerts, AIS features, and ongoing updates. However, recurring problems include sign-in friction and white-screen crashes, reliability declines after Garmin’s takeover, location/GPS data issues, and limited documentation or support. Overall sentiment is mixed: solid features and usefulness, but stability and accessibility concerns hinder daily use.
Pros
  • Easy install and intuitive interface across iPad and iPhone.
  • Remote boat data access; works well when away from the vessel.
  • Battery voltage alerts and voltage history.
  • AIS visibility and the ability to hail a boat by name.
  • Ongoing improvements with updates.
Cons
  • Frequent sign-in issues and forced re-authentication; lack of persistent login and no Face ID.
  • White screen / blank screen on boot or login; app locks up after updates.
  • Perceived degradation in reliability and support since Garmin acquisition.
  • Location data permissions and GPS/location errors.
  • Limited in-app documentation and inconsistent product support.

Needs documentation. I cannot figure out what the wind direction is try to tell me when I click on 2 hours and 24 hours. The colors have no meaning without documentation. And Garmin tech support has no idea either.

The average rating says it all - a solid concept - just works poorly. Do not depend on this app and the system for crucial info.

Doesn’t work. When I open it, there is no option to “create an account” No product support. Clearly a broken app forgotten by Garmin
