If your position fixer sends magnetic bearing, check that the variation is
correctly entered into it.
The calculation involves comparing the course and speed over the ground,
from the position fixer, to the course and speed of the boat through the
water, from dead reckoning. Any differences are due to the tidal set and drift
and can be displayed as such. To make this accurate the dead reckoning
really requires Leeway input and this in turn requires a heel angle sensor to
measure heel angle.
The damping on this function is adjustable and this can be important. In
rapidly changing tidal situations you need to lower the damping right down to
be able to see changes quickly. Conversely in a steady tide or current the
longer time the calculation is averaged over, the more accurate the results
will be. The lag in the position fixer’s ability to adjust to rapid changes in
direction, such as tacks, should also be considered when using the results of
this function. When making numerous tacks, readings should be treated with
caution.
