Own Ships Symbols
2.6.1 Circle
The circular symbol is a fixed size symbol (it does not adjust to the scale of the
chart). The circular symbol appears when the ECDIS is not receiving information
from any navigational devices, or if the scale of the chart is such that the ship
cannot be drawn in its relative size. It is also used during dead reckoning
(simulation). It has a directional arrow displaying the ship‘s heading as well as a
perpendicular shipboard line marking port and starboard sides.
This arrowhead displays the expected ships position after for example 6min.

of the chart. This symbol is used at all times except when the ECDIS is not
receiving navigational information or when the ship cannot be drawn to scale. It
also has a directional arrow displaying the ship‘s heading and expected ship
position after desired time.
