CORTEX V1 is a VHF radio system combined with AIS and remote vessel monitoring from Vesper, with a tethered touchscreen handset.

VHF Reimagined

Cortex is a revolution in marine technology that will change your VHF experience forever with an intuitive touchscreen engineered to withstand the rigors of the harsh marine environment.

The power of VHF and AIS combined

Cortex is the world’s first VHF with high speed SOTDMA AIS transponder technology, making your boat visible to others. A built-in heading sensor tells other vessels your direction, helping them more accurately predict potential collisions. See critical information about vessels, AIS Aids to Navigation and man overboard devices on your MFD, mobile or Cortex handset.

Collision Avoidance & One-touch DSC

Cortex continuously calculates collision risk ad warns you with voice annunciated alerts. View crossing situations, navigation light sectors and perform trial maneuvers while talking on the VHF radio. Initiate direct calls (DSC) with other vessels by simply tapping the vessel on your handset touchscreen. Push to talk to quickly hail another vessel when every second counts.


Cortex combines built-in sensors, external sensor inputs and NMEA2000 connectivity with free basic monitoring. Using cloud connectivity, you can view twice-daily updates of power, location, wind, depth, bilge, temperature and more on your smartphone.

Anchor Watch on board and ashore

By combining your position and heading, Cortex will determine if your anchor drags. If your boat moves outside your anchor swing radius the alarm will sound on Cortex handsets, connected speaker and your smartphone. Receive alerts while ashore via the Cortex Monitor App on your smartphone


Cortex HUB

Cortex M1 Hub is a full Class B SOTDMA smartAIS with out-of-the-box monitoring. Cortex V1 combines Cortex M1 with Cortex H1 Tethered Handset to provide full VHF functionality. Optionally add H1P Portable Handsets for even greater freedom on board.

Cortex is the world’s first VHF with high speed SOTDMA AIS transponder technology making your boat visible to other vessels your direction, helping them more accurately predict potential collisions.

Configure and monitor the Cortex system and receive alerts to a connected smartphone on the Cortex Onboard App or receive alerts and control devices on the boat remotely using the Cortex Monitor App.
