The Intelligent Boat

SOTDMA smartAIS transponder with remote vessel monitoring and control

Smart & Connected

An intelligent boat can see what you can't. It predicts collisions with other vessels and knows when someone falls overboard. It knows when your anchor is dragging. It would tell you something is wrong, whether you're onboard or ashore. Cortex. The brain of your boat.

The smartAIS Advantage

smartAIS proactively alerts you of potential collisions, anchor drag and man overboard situations. smartAIS consumes very low power and continuously alerts even if your power intensive MFD or smartphone is switched off.

Collision Prevention

smartAIS combines GPS, AIS and heading data with smart logic to proactively warn you of collision risks.

Clearly see the highest risk vessels. When using a Cortex handset, smartphone, or tablet, make trial maneuvers to see a simulation of where and when your paths will cross.

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.

Man Overboard (MOB)

When Cortex detects an AIS MOB activation it immediately sounds the alarm.

Compatible with all AIS MOBs, you will see where the MOB was first activated along with continuous updates to its location, bearing, and range. Get clear information and take the best course.

Label AIS MOB devices with crew names for easy identification.

Pressing the dedicated MOB button activates a trackback mode on all handsets and marks the MOB on NMEA 2000 connected MFDs.

Advanced SOTDMA Technology

SOTDMA is the latest AIS technology with 5W power output, making your boat visible over a longer distance.

With faster and more frequent transmissions of your position to other vessels, you'll be safer, especially at speeds of over 14 knots.

Connect via WiFi

Receive alerts on your smartphone, tablet, or smartwatch anywhere onboard.

Connect up to 10 WiFi devices to receive and manage alarms, view AIS information and instrument data.

Integrate Cortex to your NMEA 2000 network and use your mobile devices to view information your instruments provide.

10Hz GPS Update Rate

With 10Hz GPS updates, your vessel position is more accurately plotted.

When you connect other devices to your Cortex GPS using NMEA 2000 or NMEA 0183, all onboard equipment benefits from our superfast GPS.

Integrated No-Loss Splitter

Our integrated no-loss splitter allows you to share a single antenna with another VHF and delivers optimum performance for both your VHF and AIS.

Low Power Consumption

With low input power, you can keep Cortex always on, so you are always visible and always watching. Receive alerts without the need for power-hungry MFDs.

Cortex Will Get Smarter.

New features and capabilities are downloaded automatically to the Cortex Onboard app for easy updates to Cortex via WiFi whenever convenient.

Remote vessel monitoring and control

See your boat's status, receive alerts, and control devices.

Easy setup, no fee

With built-in sensors, you can see twice-daily updates of your boat's location, battery level, true heading, ambient temperature, and barometric pressure.

Connect to your NMEA network and monitor more - wind speed direction and water depth.

As long as your smartphone and boat have cellular access, you can know your boat is safe and secure. No subscription, no hassle.

Real-time monitoring and control

Subscribe to a Cortex Monitor Plan to receive alerts, see real-time information about your boat, and remotely control devices like lighting, air conditioning, refrigeration, or ice-makers.

Whether you've left your boat, at anchor, or at the marina, know exactly where it is and what's happening onboard.
