Speed Calibration

To ensure that the boat speed (and distance) is accurate it is necessary
to calibrate the speed to take into account variations in water flow
between different hulls. Adjustment is made by multiplying the speed
through the water (V) by a percentage calibration factor.
It is essential to carry out this procedure at a time when little or no tide
is flowing.
To take account of tidal flow, the calibration run should be carried out
twice, once with the tide and once against the tide. The calibration
percentage factor should then be set to the average of the factors
determined by the two runs.
To enter a Log Calibration Factor:
With the vessel under power, steer a straight course allowing the boat
speed reading to settle to a constant value. Check the GPS is showing
a constant SOG.

Should you be unable to carry out this procedure due to strong tidal
conditions or poor GPS information there is further information regarding
