Item Descriptions
1 Wind arrow — wind direction is displayed as a yellow line with
solid arrow heads pointing towards your vessel, indicating the wind
direction. The width of the arrow indicates the wind strength.
2 Tide arrow — tide is displayed as a blue line with solid arrow head
pointing away from your vessel, in the direction of the tidal set. The
width of the arrow indicates the tide strength.
3 COG (Course Over Ground) vector — a green line indicates the
vessel's actual course. A double arrow head is used if the vector
length is set to a value other than infinite.
