Unfortunately this is an annoying Signal K bug. AIS data may override the boat name in some edge cases. It happens more frequently if you happen to have a DataHub but we have seen it happening without a DataHub too.

Signal K team has been working on a fix, here is a link to the tracker: https://github.com/SignalK/signalk-server/pull/1833

In the meantime, restarting Signal K should solve it.

Yes, perfect!

Hi,
thanks for your immediate response ... highly appreciated. When reading your advice, it popped up that I already had once the same problem and it was and still is hökens-anchor-alarm https://www.npmjs.com/package/hoekens-anchor-alarm after deleting the anchor-alarm everything is back to normal. Thank you.

Perfect. Thanks!

Here is an example of how additional data is captured per trip, from our logbook:

This will show up for you the next time you complete a trip, based on custom monitoring data you have added.

Thank you so much.
I'll try that.

OK thank you it's work perfectly !!! Very nice ...

Awesome thanks

Makes sense. I think we just won't recommend that particular sensor, since it's refresh rate is r fast enough for monitoring.

I'm really excited to have SailLogger on the boat. That you for making it available.

Hi Bill,

Actually, you didn’t miss it. We do have the capability to import GPX files, but this option isn’t available in the UI for several reasons:

Granular Data Requirements: Importing GPX files can be tricky because Saillogger requires granular data logging. Not every GPX capture provides the necessary detail, which may lead to inaccurate identification of trips and statistics. Stateful Design: Saillogger is stateful by design. Importing a track risks breaking this state by introducing inconsistent data over time periods that have already been processed. (Imagine a boat "beaming" in and out over a couple thousand miles in a single day!) Streamlined User Experience: Our data model is extremely rich, but to ensure a streamlined experience for regular users, we simplify what is processed and displayed. In practice, we normalize every account to a single boat, maintaining that boat’s state in great detail. For users with multiple boats, we create separate accounts.

That said, we’d love to help you add your deliveries. If you send us the GPX file, we can experiment with it to see if the import process makes sense.

We would need to have a plan for a clean fallback to ensure that Harmonie’s logbook and track remain accurate!

We have also discussed this with Victron. They will address it for all Cerbo GX Mk2s.

The log from today's boating looks much better. Thanks !

Hi @WJGreene2025, Saillogger is a feature-rich tracking and advanced monitoring system designed to go beyond basic location tracking. It offers comprehensive features such as:

Detailed trip logs: Automatically segmented into individual trips, including specific location names where you anchor, dock, or moor.

Micro-blogging: Easily document and share your journeys.

Detailed statistics: Gain insights into time spent at anchor, dock, mooring buoys, or home/foreign ports, and track visits to different countries or regions.

Advanced NMEA2000 monitoring: Ability to associate any custom NMEA2000 data with trip logs for future reference or diagnosis.

Saillogger is compatible with multiple data sources, including PredictWind's DataHub and Victron GX devices. Some features, such as NMEA2000 monitoring, depend on the underlying platform.

You can continue using DataHub as a data source while benefiting from Saillogger advanced tracking and analytics capabilities.

If you decide to transition from DataHub to a Victron-based solution, Saillogger can also support importing your historical tracks from PredictWind.

I hope this helps. Feel free to ask if you have any questions or need further clarification.

Thank you Bill, what a wonderful feedback—you made our day!

We are following Harmonie’s journey and hope we can cross waves somewhere in the Bahamas this season, so we can cheers in real life. Safe travels and happy Saillogging until then!

I'm very glad to hear that we could help and that your issue with MarineTraffic has been resolved! Re-installing SignalK on the Cerbo GX can indeed come in handy when the installation becomes unstable, and several other users have found this approach helpful.

Your idea to create step-by-step instructions is excellent. Please post them here, and we can update our FAQ to include a reference. We're also considering developing a video tutorial for your Youtube Channel that walks through the re-installation process, along with some additional tips to enhance the user experience on the Cerbo GX.

Nice, please share when done!

Looks like there was indeed a problem with zoom. This has been addressed and a fix has been deployed. Thank you for bringing this to our attention.

Hi, unfortunately monitoring page is not customizable right now but we will file a feature request for this.

What were the timestamps for navigation.position? Timestamps are critical here. Signal K may display positions even if they aren’t being refreshed, but Saillogger will only use positions if they are actively refreshed. When you encounter an issue like this, please verify those timestamps.

Generally, there’s no technical reason why a GPS position in Signal K wouldn’t appear in Saillogger. Saillogger retrieves data directly from Signal K, so as long as the position is present and refreshing (refreshing is essential), it should definitely capture it.
