2.9.31 Next Leg Wind Information
Menu heading: WIND
Function text: N/L AWA or N/L AWS

rate: 1Hz
Units: Knots and degrees
Notes
1. Apparent wind speed and angle.
2. Corrected for tide if required.
3. Requires a Performance Processor.
Next Leg information is a prediction of the conditions of
apparent wind speed and angle that you will meet on the
next leg, and is calculated from the current true wind speed
and direction, and a bearing that you enter for the next leg
course. From this the true wind angle on the next leg is
calculated, and using the polar tables the corresponding boat
speed is given, and hence the apparent wind speed and
angle.
Should the leg be upwind or downwind, rather than free, the
h2000 calculates on the basis of the true wind angle for the
optimum VMG on the advantaged tack; this is indicated by
the position of the small bar at the top or bottom of the
digits. The tide calculated by the h2000 can be applied to
the calculation if required.
The Next Leg Bearing is entered as a CONTROL option
under N/L AWA, found by:

At the same menu level is the tidal option where entering a

tide from the calculation, found by:

The tide is calculated by the Performance Processor when a
position fixing system is connected, see Para 2.9.40.
