Memo
• When using 1-axis log, heading speed component can be detected, but transverse speed
component cannot be detected. Then leeway effect (component drifted by wind) cannot be
detected.
• When using 2-axes log, its accuracy in shallow waters may be deteriorated, and its speed
in deep sea areas may be unable to be detected.
• When using a GPS, COG accuracy is less than ±3° at speed: from 1kn to 17kn, and is less
than ±1° at speed: more than 17kn.
