4.2 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 where little or no tide

is flowing.

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.

Press and hold the button for 2 seconds to enter Setup

Press the button repeatedly to scroll to the SETUP SPEED

Chapter

Press the button to advance to the Speed Calibration page

Press the button to enter Edit Mode

Press the and buttons to change the Calibration

Factor until the Speed reading displayed matches the GPS

SOG reading

Press the button to exit Edit Mode

Press and hold the button to exit Setup and return to normal

operation.

Should you be unable to carry out this procedure due to strong tidal

conditions or poor GPS information there is further information regarding

Speed Calibration using a measured distance on the Raymarine website
