Forecast wave indication
Colors can be used to indicate forecast wave height. The highest
waves are dark red, while the lowest are blue.
You can define how the color codes are used to identify the wave
height. Refer to "Adjusting color codes" on page 165.
Forecast wind barbs
Forecast wind barbs can be shown or hidden on the weather panel.
Wind barbs
The rotation of the wind barbs indicate the relative wind direction,
with the tail showing the direction the wind is coming from. In the
graphics below, the wind comes from the northwest.
Wind speed is indicated by a combination of small and large barbs
at the end of the wind tail.
Zero knots / Indeterminate wind direction
Small barb = 5 knots
Large barb = 10 knots
Arrow barb = 50 knots
If a combination of 5 and 10 knot barbs are shown on a tail, then
add them together to give you the total wind speed. The example
below shows 3 x large barb + 1 x small barb = 35 knots, and 60
knots indicated with 1 x arrow barb + 1 x large barb.
Wind speed: 35 knots
Weather icons
Several weather icons are available to show current or predicted
