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.
