Leeway is the angle between the boat’s heading and course
through the water. The difference is caused by the sideways
slip that the boat has when going upwind. For the h2000 to
be able to measure this it needs to know the heel angle, and
hence a sensor must be fitted. Leeway is of great importance
in the calculation of Dead Reckoning, since the 3º to 4º of
leeway can considerably affect the dead reckoned position.
2.9.25 Layline Distance
Menu heading: PERFORM
Function text: LAYLINE
Update rate: Provided by position fixer
Units: Nautical miles
Note
Requires NMEA 0183 interfaced position-fixing system
transmitting the ZDL sentence.
If tacking upwind or downwind to a waypoint, some
position fixing systems will provide layline information
based on a pre-defined tacking angle (usually adjustable).
This function displays the distance off both left and right-
hand laylines by alternating the display between the two. An
L or R is shown in the right hand digits to signify Left or
Right laylines respectively. This function can be particularly
useful when nearing a waypoint. When the value reaches
zero, it is time to tack or gybe for the mark. The calculation
should be corrected for any tidal offset.
2.9.26 Local Time of Day
Menu heading: TIME
