This is the Tactician's greatest ally in the search for the right
wind shifts. It shows the compass direction that the wind is
coming from regardless of the boat's heading. It is
calculated from the true wind angle and heading, and is
corrected for calibration errors by the true wind look-up
table. It is very important to understand the function of this,
in order to have an accurate true wind direction. It is fully
explained in Chapter 3 - Calibration.
2.9.52 True Wind Speed
Menu heading: WIND
Function text: TRUE W/S
Update rate: 2Hz, Hydra
Update rate: 4Hz, Hercules
Units: Knots, metres per second
Notes
1. Corrected for masthead and other errors via the
look-up table, see Chapter 3 - Calibration.
2. Variable damping 0-99 seconds.
3. Dynamic damping available.
When the boat is sailing downwind, the air passing over the
mast is accelerated, and in the past this has tended to make
the true wind speed over-read. The h2000 has introduced a
calibration for this that will allow you to correct out the
error; it is explained in Para 3.4.
