7.10 Sailing Directions, Tidal Tables, etc., Features of
Vector Charts
Vector charts contain sailing directions, tidal tables and other textual and picture information which are not
immediately visible on the chart. This information forms an integral part of the legal ENC chart which can fulfil
SOLAS requirements. As a navigator you should check them as well as you check the visible chart when you do
your planning and when you perform navigation.
Because these features are not permanently visible on the chart as they used to be in case of a paper chart, the chart
radar has special symbols to highlight the locations from which you can use the Info request to know additional
information about the above-mentioned features. Below are examples of these symbols. For further details, see
section 7.13 Requesting Information About Vector Chart Objects.
A grey box is used to show that Tidal information is available for Info request by cursor pick.
Note: The visibility of the grey box symbol is controlled by the item "Depth contours, magnetics,
currents" in the Other 1 page of the Chart Display dialog box.
A magenta-colored symbol is used to show that additional textual or picture information such as
sailing directions are available from Info request by cursor pick.
Note: The visibility of the magenta symbol is controlled by the item "Additional information
available" in the Other 1 page of the Chart Display dialog box.
