Formerly the mainstay of all offshore navigation, now with such widespread
use of electronic position fixing equipment it is more often used as an
essential back-up. It can be particularly effective as an indicator of the net
course steered on long offshore legs. Both the course as a bearing from the
start point, and its distance in nautical miles, can be displayed as separate
functions. If the heel angle sensor is fitted then the course calculation will
include leeway correction.
In the worst case, a Man Overboard (MOB) situation, immediately resetting
the Dead Reckoning (DR) will bring the vessel back to the MOB position. DR
is the course over the water and not over the land as would be given by a
position fixer.
