2.11.38 True Wind Direction
Menu Heading:
WIND
Function Text:
TRUE DIR
Update Rate:
Once per second
Units:
Degrees magnetic
Notes
1. Wind angle relative to magnetic compass point.
2. Corrected for masthead and other errors via a Look-Up Table (see Part 3 -
Calibration).
3. Damping control via true wind speed.
This is the tactician's greatest ally in the search for the right wind shifts. It
shows the compass direction of the wind regardless of the boat's heading or
speed. True wind direction is calculated from the true wind angle and
heading, and is corrected for calibration errors by the true wind look-up table.
A full explanation is given in Part 3 - Calibration.
2.11.39 True Wind Speed
Menu Heading:
WIND
Function Text:
TRUE W/S
Update Rate:
Once per second
Units:
Knots, metres per second
Notes
1. Corrected for masthead and other errors via a Look-Up Table (see Part 3 -
Calibration).
2. Variable damping 0-99 seconds.
True wind speed is required by the Trimmers for decisions on sails, and to
check their trim as the wind changes.
When the boat is sailing downwind, the air passing over the mast is
accelerated and tends to make the true wind speed over-read downwind.
The Hydra has a calibration to correct for this which is explained in Part 3 -
Calibration.
