Sail¶
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.

Abbreviation | Description | Units |
---|---|---|
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 |
HDT | Heading True | degrees |
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.
