Vesper Marine's Cortex VHF radio ready to ship

(AUCKLAND, New Zealand) — Vesper Marine, a leading manufacturer of innovative marine electronics, has announced that its marine VHF technology Cortex has completed certification requirements and will ship to distributors beginning late July. Cortex is the world’s first marine VHF radio with wireless touchscreen handsets, built-in Class B SOTDMA smartAIS transponder and remote vessel monitoring and will be available through Vesper Marine’s network of distributors and dealers.

“With the intention of completely changing the paradigm of onboard VHF communications, the development of Cortex has been years in the making,” said Carl Omundsen, chief technical officer, Vesper Marine. "We are delighted to announce Cortex has received regulatory approvals for North America, Europe and Australasia (FCC, IC, CE). Boaters will soon get the full benefits of the most advanced, feature-rich VHF on the planet.”

Cortex offers safety by alerting boaters of collision risks, providing key information about nearby vessels and making it easy to communicate directly with them. The handset’s touchscreen makes typically complicated VHF functions easy to use. For example, touching a vessel onscreen and pressing “call” makes a DSC call directly to that vessel. Cortex continuously calculates crossing situations and even allows trial maneuvers – all while a boater talks on the VHF radio. Up to 10 handsets, either tethered or portable, provide up to 85 dBA of clear audio and are built to survive the harsh marine environment. A 10W output enables audio and alerts through an external speaker, even while handsets are turned off. Cortex includes dual-watch, favorite channels and one-handed operation via the click-wheel. Pressing the dedicated man overboard (MOB) button activates a track back mode on all handsets and marks the MOB waypoint on NMEA 2000 connected multi-function displays (MFDs). 

Cortex also includes remote vessel monitoring, enabling boaters to know their boat is anchored securely while enjoying a visit ashore by checking on the Cortex Monitor app, available from the Google Play or Apple App Store. Standard monitoring is available at no charge to all owners. An upgrade plan offers more advanced monitoring features such as Anchor Watch, control of on board devices and real-time updates. To make sure everyone has an opportunity to experience the benefits of the upgraded plan, all users receive a free three-month trial.

Engineered for marine durability, the tethered Cortex H1 and portable Cortex H1P handsets feature a 4-inch Gorilla Glass multi-touch display. Wet finger and glove capable, the touchscreen is optically bonded for wide-angle and sunlight viewability, even in the harshest midday sun. The Cortex M1 hub is enclosed in a unique thermal polymer housing without risk of corrosion and is completely sealed with an IPX8 (submersible) rating. It includes an integrated no-loss splitter so a single VHF antenna can be shared by Cortex and an existing VHF radio. All ports are galvanically isolated to protect from corrosion, electrical surges and ground loops. The Cortex M1 is available separately as a full-function Class B SOTDMA AIS with remote vessel monitoring and control and is VHF-ready. Simply add Cortex handsets to access full VHF communication functionality or purchase the Cortex V1 package which includes the M1 hub and an H1 handset.

Cortex will be available from authorized Vesper Marine resellers worldwide along with a selection of installation accessories. For more information on Cortex visit For more information on Vesper Marine or its entire product line, visit
