Vesper's Cortex has redefined VHF by offering high speed, advanced monitoring in a simple, easy-to-use package that’s proving popular in larger trailer boats.

Trailer boats left in a driveway or at the bach during the week are vulnerable to theft and damage, but Cortex’s unique Geofence feature offers full-time monitoring and protection.

Using its remote monitoring and control features, owners can easily check their boat’s systems and alleviate problems. For example, they can check their batteries are fully charged and remotely switch on a charger if charging is required.

The Cortex Monitoring App provides twice daily updates of onboard water and fuel levels, monitors fridges or switches them on ready for when the crew arrives.

Other popular features include Cortex’s in-built smart AIS, its hands-free VHF utility and the useful Anchor Watch function. Cortex accommodates multiple wired and wireless handsets.

Cortex is now available through Lusty & Blundell’s nationwide marine dealer network.



Vesper Marine’s Cortex is the world’s first VHF radio with wireless touchscreen handsets, a built-in Class B SOTDMA smartAIS transponder and remote vessel monitoring.

Cortex includes dual-watch, favourite channels and one-handed operation via the click-wheel.

The dedicated MOB button activates a track back mode on all handsets (up to 10) and marks the waypoint on NMEA 2000 connected multi-function displays (MFDs).

Vesper Marine’s smartAIS technology combines navigation sensor data with intelligent alarm management that prioritises alerts.

Basic monitoring using cellular connectivity is free while a Cortex Monitor Premium subscription unlocks real-time vessel status, alerts and device control for boat systems. Cortex Onboard and Cortex Monitor apps are available for iOS and Android with new features and capabilities downloaded automatically via WiFi. Cortex integrates with leading marine MFDs, sharing AIS positioning information and boat sensors.
