Before you sail: set Telemetry Logging to 5 Hz or 10 Hz

For the best accuracy in tacks/gybes and short maneuvers, record your session at 5 Hz (minimum) or 10 Hz (best).

Important: If your device logs at a lower rate, Ktool will still work — but maneuver detection and graphs will be less detailed.

In the Vakaros mobile app

Set the logging rate like this:

  1. Open Boats
  2. Select your boat
  3. Open Device
  4. Find Telemetry Logging
  5. Select 5 Hz or 10 Hz
Screen recording: Vakaros app — Boats → Boat → Device → Telemetry Logging.

Export your session from Vakaros: VKX or CSV

Export as VKX (recommended) or CSV (works well), then upload to Ktool.

Recommended: VKX

Use VKX for the most complete Vakaros dataset and the best match with Ktool analysis.

Alternative: CSV

Use CSV if you prefer a readable table format. Make sure it includes timestamps + GPS.
