[True]: The wind angle measured with true North as the reference angle and the
wind speed as if the ship is stationary. "T" is displayed on the screen.
[Theoretical 360°/180°]: Theoretical or calculated wind angle. The wind angle
relative to the ship’s bow and the wind speed as if the ship is stationary. The wind
graphic scale for [Theoretical 360°] indicates 0° to 360°, for [Theoretical 180°] in-
dicates 0° to 180° for port and starboard. "T" is displayed on the screen.
[Relative 360°/180°]: Relative or apparent wind angle. The wind angle relative to
the ship’s bow and the wind speed relative to the moving ship. The wind graphic
scale for [Relative 360°] indicates 0° to 360°, for [Relative 180°] indicates 0° to
180° for port and starboard. "R" is displayed on the screen.
Note 1: The same abbreviation "T" is used for both [True] and [Theoretical 360°/
180°].
Note 2: The indication of the wind angle (port or starboard) is displayed at the bot-
tom of the screen when you select [Theoretical 180°] or [Relative 180°].
