align the log speed with actual vessel speed.

1 Point Speed Calibration
To perform a 1 Point Speed Calibration follow the steps below.
Prerequisites:
• For best results SOG data should be available, or an alternative method of estimating vessel speed
must be used (e.g. vessel speed can be estimated using Nautical Measured Mile Markers or
similar landmarks of a known distance apart).
• You will need to be underway, with sufficient space to maneuver unhindered.
• In order to achieve accurate results, water conditions must be calm with zero tide and zero current.
