Why this orange maneuver was detected as tack? It looks the same as gybes.

And no, I have not done any tacks in this session 🙂

Tack/jibe detection relies on the wind direction combined with your heading change — if the wind direction is slightly off, the algorithm can misclassify the maneuver.

Could you send the original file so I can take a closer look? In the session, tap the download button and select “Original”, then send it to [support@sunbits.de](mailto:support@sunbits.de).

**V12 of the analyzer is out and fixes jibe detection.**

To reanalyze your session: open it → Info section → tap **Reanalyze**.

Thanks for sharing the file — it directly helped improve the algorithm.
