module load sail
This module creates a sailing dashboard window that displays information relevant to sailing vehicles. There are two meters on the left that display apparent and true wind speed and angle. On the right is a panel of instrument displays showing wind speed and angle, speed through water and true heading.
|AWA||Apparent wind angle||degrees|
|AWS||Apparent wind speed||knots|
|TWA||True wind angle||degrees|
|TWS||True wind speed||knots|
|STW||Speed through water (ground speed for land vehicles)||knots|
Wind angle is relative to the front of the vehicle and is positive in a clockwise direction. True wind speed and angle are calculated from apparent wind speed and angle accounting for the speed through water, however in the absence of a log they are calculated with respect to ground speed.
