What people are saying

"Cortex is poised to be an onboard technological juggernaut."

“...it’s not a VHF radio…but it is. It’s not an AIS…but it is. It’s not a MOB system…but it is, and it’s a whole lot more”
- Lenny Rudow, IBEX Innovation Awards Judge

"The ability to just touch the screen and call up directly another boat is a pretty neat feature”
- Nigel Calder, SAIL Magazine & Pittman Innovation Award Judge

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.

Be armed with critical information about vessels, AIS marks (AtoNs) and man overboard devices on your MFD, mobile or Cortex handset.

Collision Avoidance

  • Alert
  • Inform
  • Call

Cortex continuously calculates crossing situations and generates collision alarms for critical action, alerts if your anchor is dragging and activates MOB alarms for immediate retrieval. Instead of ambiguous bells or tones, Cortex sounds the alarm with voiced alerts that escalate until acknowledged.

Continuously view crossing situations, navigation light sectors and complete trial maneuvers while talking on the VHF radio. See critical information that is easy to understand and take action.

Initiate direct calls (DSC) with other vessels by simply tapping the vessel on your handset touchscreen. Initiate VHF calls to friends or quickly hail another vessel when every second counts.

Monitor

Cortex combines built in sensors and NMEA2000 connectivity with free basic monitoring. Using cellular connectivity, you can view twice-daily updates of power, location, wind, depth, bilge, temperature and more on their smartphones. The Cortex Monitor Premium subscription unlocks real-time vessel status, instant alerts and device control for boat systems like refrigerators, icemakers, lights or heaters.

Anchor Watch

Sleep soundly or explore with abandon knowing that your boat is exactly where you anchored it.

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 and your smartphone.

Receive alerts while ashore via the Cortex Monitor App on your smartphone.

Want to know if water depth, wind speed or direction changes while anchored? No problem, Cortex will keep watch and alert you.
