ABOUT
Before leaving the marina, we tend to think about the route, the weather and battery charge. Once under way, it helps to have the relevant readings together. That is the purpose of Victron’s GX Boat Page, a dedicated display for electric and hybrid boats.
On 22 September 2026, Victron released Venus OS 3.80, a software update for GX devices. It expands the information available on that page.
What does version 3.80 add?
GX Boat Page gains range estimates, temperature data, regeneration and shore power information. GX devices also receive inbound NMEA 2000 alarms.
Why might that matter on your boat?
The following are examples of how the information could be used, rather than a promise of the same result on every boat:
- Remaining range: when considering another leg of a trip, the estimate offers an extra reference alongside battery information. It is not a guarantee of the distance your boat will actually cover.
- Shore power: at the berth, you can review the available information about this source while checking the energy system before your next outing.
- Temperature and regeneration: temperature readings add context when monitoring the system; regeneration information is useful in a configuration that supplies those data.
- NMEA 2000 alarms: receiving inbound alarms allows information from the connected network to reach the GX device.
What should you check on your own installation?
GX Boat Page adapts to the available data. Victron’s description explains configurations using NMEA 2000 or a SmartShunt set up to meter the electric drive. The information displayed depends on the equipment and its connections.
Before updating, check your GX model, installed version and system settings. Victron’s manual describes updates via the internet or microSD/USB, followed by a check of installation settings. Plan the update as part of your boat’s maintenance.
