Drift and Set

Because the boat is not always moving directly in the

direction of its compass heading you need to know the

direction (SET) and the speed (DRIFT) by which the boat is

being pushed off course. Tactically this is important when

assessing when to tack or gybe to round a mark or clear an

obstruction or headland.

Your Maxi Display automatically calculates this information using

information from your GPS, boat speed and compass. The calculated

set angle is rounded to the nearest ten degrees.

Set and Drift as calculated includes the effect of both tide and

leeway. Therefore the value will be different on opposite tacks,

depending on whether the boat is sailing into or against the tide.

This will be especially noticeable when the tidal effect is small.

In conditions of little tide, this calculation is very sensitive to

inaccuracies in the calibration of your speed and compass

transducers. It is not recommended that you rely on the accuracy

of this calculation when the tide speed is less than one Knot.

A flashing indicator will alert you if the calculated values are

uncertain.

See the Calibration Guide for information on how to maximise the

accuracy of the calibration of your speed and heading transducers.
