Getting started

Runs on what your boat already has

If your boat runs a Victron GX device, you already have the hardware. A Raspberry Pi or any system running Signal K works too, and PredictWind users can simply connect their tracking link.

  1. Connect your boat

    Install the free Saillogger app on a Victron Cerbo GX or any GX family device, set up a Raspberry Pi with Signal K, or link your PredictWind tracker. See the technical requirements.

  2. Cruise. It logs itself.

    Saillogger notices when you leave the dock, logs the whole trip, names your departure and arrival, and records distance, speed and wind. Nothing to start, nothing to forget.

  3. Follow from anywhere

    Check your boat and your logbook on the web or in the iOS and Android apps, get alerts when something changes, and share a private live link with friends and family.

Loved by boaters

When we switched our offshore communications to Starlink, we needed a new solution for our realtime web tracker. We evaluated several potential solutions, and Saillogger was the clear winner. It has all the features we wanted and more. The automated log has just been a great system for us.

Saillogger takes all the tedious work and risk of error out of passage logging. A single, safe place to log and share all of those hard-earned sea miles! It really came into its own when we compiled our logs for our recent RYA Yachtmaster exams.

We have been using Saillogger since 2021 and it has been keeping great track of us ever since. Saillogger has been integral to our log keeping, faithfully tracking in the background without any effort from us.

I have worked in the Marine Electronics industry and can say that Saillogger is ahead of the curve. ... It just works! The quality of the code is evident and the thoughtfulness of the design is excellent.
