Relative Motion - Raymarine A65 Owner's Handbook Manual

Chapter 4: Using the Chartplotter 89
Course Up (C-UP)
In Course Up mode, the chart picture is stabilized and shown with your current
course over ground (COG) upwards. As your boat's COG changes, the ship symbol
moves accordingly. If you select a new course, the picture will reset to display the
new course upwards. As long as course data is received, the indicator 'Course-Up'
or 'C-UP' appears in the Status Bar in white text. If course data is lost, the indicator
changes to '(Course-Up)' or '(C-UP)' in amber text.

Relative Motion

Relative Motion refers to the relationship between the chart and your boat when
moving. Relative Motion mode is set when you press FIND SHIP. The position of
your boat is fixed on the screen and the chart picture moves relative to your boat.
The RELATIVE MOTION indicator appears in the Status Bar at the top of the screen
in white text and without parentheses.
Relative Motion
When you pan the chart, the cursor is no longer placed over the boat and Relative
Motion is suspended. This enables you to view another area of the chart while
navigating. This mode is also referred to as true motion because the chart is fixed
and the boat moves in true perspective to fixed landmasses on the screen. As the
boat's position approaches the edge of the screen, the chart picture is
automatically reset to reveal the area ahead of the boat.
In True mode, RELATIVE MOTION indicator in the Status Bar now appears in
amber text and is encased in parentheses '( )'. To reset Relative Motion and return
your boat to the center of the screen, press FIND SHIP.
Note: This setting is returned to Relative Motion at power-on.
