Transform your boating experience with Victron GX

A guest blog post by Ilker Temir, founder of Saillogger and full-time cruiser.

As we spend more time cruising, it’s increasingly clear that Victron installations are becoming a standard feature on modern boats. Whether it’s upgrading to lithium-ion batteries, installing solar panels, or optimizing electrical systems, these projects frequently include multiple Victron devices. In fact, it’s rare to find a boat with a serious solar setup that doesn’t include a Victron MPPT controller. While many of these boats also feature a Victron GX device, full integration with the rest of the boat’s electronics remains surprisingly uncommon—even though this integration can significantly enhance the boating experience out of the box.

In this post, I’ll explore some of the key enhancements that a Victron GX device brings to your boating experience. I’ve categorized these improvements into three distinct tiers:

Each category adds layers of functionality, enabling you to tailor your marine electronics to suit your needs and preferences. Let’s dive into them in more detail.

 

Out-of-the-box enhancements

By simply connecting a Victron GX device to your boat’s NMEA 2000 network, several powerful features are immediately unlocked:

Data from Power Systems on a Garmin Chartplotter

NMEA 2000 Tank Levels displayed on Victron GX

These features work right out of the box, providing a solid foundation for monitoring and managing your boat’s power, navigation, and environmental systems and sensors in an integrated manner. Victron’s Marine Integration Guide covers these in detail.

 

Marine extensions with Venus OS Large

More advanced marine capabilities become available by upgrading the Victron GX firmware to a Venus OS Large Image and toggling on a simple setting. This upgrade enables marine extensions for Victron GX, unlocking the potential of a powerful platform called Signal K, enabling a range of new functionalities.

By simply enabling marine extensions, you can share data from your instruments with popular navigation software, including Navionics, AquaMap, TimeZero, Coastal Explorer, or OpenCPN, providing seamless integration and enhanced usability for your navigation and marine data.

Advanced Integration with Signal K

Signal K, enabled by Venus OS Large Image, is an incredibly powerful platform. It offers a range of useful features right out of the box, but you can unlock even greater functionality by adding plugins or extensions with just a few simple steps. These customizable enhancements include:

Since each of these extensions needs to be enabled individually, you may need to follow a few additional steps to activate them or fully utilize their capabilities. These steps allow you to customize the features to suit your specific needs and maximize the potential of these powerful tools.

Saillogger Mobile App

I am also one of the active developers of these extensions and the founder of Saillogger, a service designed for simplicity and automation with a modern, user-friendly interface. Saillogger offers effortless automated logging, track sharing, advanced NMEA 2000 monitoring, and the ability to preserve your boating memories forever. It leverages the powerful capabilities of Signal K while seamlessly integrating with your boat’s systems, using the Victron GX as the central hub.

For more information about these powerful capabilities, check out the video tutorials we publish regularly. While we don’t cover every add-on, these guides can help you get started with some of the most popular features.

Conclusion

Integrating a Victron GX device with your boat’s systems unlocks a world of possibilities: boaters can choose from out-of-the-box NMEA 2000 integration, marine extensions with Venus OS Large, or advanced integration with Signal K.

Whether you’re monitoring power systems, integrating instrument data with your navigation apps, using Saillogger to provide real-time tracks to friends and family, or automating trip logs, these technologies transform your boating experience into a seamless blend of connectivity, convenience, and storytelling, making every journey more engaging and memorable.

While some features require additional steps or customization, the benefits far outweigh the effort, making your time on the water safer, more efficient, and infinitely more enjoyable.
