4.2 Marks and Events

The RayChart allows you to place symbols to record marks or events.
You have a choice of 16 symbols for each type.
Marks and events differ in the following ways:
• Marks are used to record features at the cursor position, such as
fishing buoys and anchorages. They are only graphical marks, and
you cannot edit them or add information.
The Danger Zone mark ( ) has an associated invisible "exclusion
zone" around it. You can specify the radius of the exclusion zone as
part of your setup procedure (see Section 6.2). If your vessel enters
this zone, an alarm will sound.
• Events are used to record features at your vessel's current position,
such as a good fishing spot.
Events are special waypoints. The RayChart assigns a unique
identifier to each event, in the format xxx EV, where xxx is the next
available number. The events are stored in the waypoint list, and can
be recalled and edited later (see Chapter 5).
Up to 1000 marks can be displayed on the screen at one time, and up
to 1000 events or waypoints.
