C-Map dynamic current graphic
When the Tides layer is enabled or when the Chart app is in Tides mode , the standard Current
station symbol is replaced with a dynamic Current graphic. Arrows are used to indicate the direction
of current flow. The size and color of the arrow indicates the strength of the current:
1. Yellow square: 0 Knots to 0.1 Knots
2. Yellow small arrow: 0.2 Knots to 1.0 Knots
3. Orange small arrow: 1.1 Knots to 2.0 Knots
4. Orange large arrow: 2.1 Knots to 3.0 Knots
5. Red large arrow: Greater than 3.0 Knots
Navionics dynamic current graphic
When the Tides layer is enabled or when the Chart app is in Tides mode , the standard Current
station symbol is replaced with a dynamic Current graphic. Arrows are used to indicate the direction
of current flow.
The length of the arrow indicates the speed of the current; the longer the arrow, the faster the speed.
The border color of the arrow indicates increasing or decreasing speed.
1. Red = increasing current speed.
2. Blue = decreasing current speed.
Current speed is shown inside the arrow. Current speed is displayed in user-selected speed units,
with decimals displayed in subscript. Decimals are not shown for values of 10 or greater.
If tidal conditions are “slack”, the word “SLACK” appears in a box with a Blue border.
