Chapter 4: The chart application 53
Vector length
The length of the vectors is determined by the distance your boat
will travel in a given time (This time can be set using the set up
menu) at the current speed.
Wind and tide arrows are shown on the chart as lines with solid
arrow heads pointing in the direction of the wind or tidal set. Wind
arrows point towards your boat, tidal arrows point away from your
boat. The greater the strength of the wind or tide, the thicker the line
appears.
Chart mode and orientation
Mode settings enable you to control how information is shown on
the chart, they let you change such things as how movement is rep-
resented, the position of your boat’s on-screen representation and
the chart orientation.
Orientation
Orientation settings control the way the chart is drawn in relation to
your boat’s position and course.
To set the chart orientation:
1. Press the PRESENTATION soft key.
2. Press the CHART MODE AND ORIENTATION soft key.
3. Press the ORIENTATION soft key to toggle it to your preferred
choice.
Orientation options:
• North Up (N-Up)
This is the default mode with the chart static and orientated with
true north to the top of the screen. As your boat’s heading
changes, the boat symbol rotates accordingly.
• Heading Up (H-Up)
In this mode the on-screen boat symbol remains static, with the
current heading facing the top of the screen. When you change
the boat’s heading the chart rotates accordingly. However, to
prevent continual chart rotation as your boat yaws, the chart will
only update if the heading change is 10
o
or greater. You cannot
select Head-Up mode if the motion mode is set to True.
• Course Up (C-Up)
In this mode the chart is static and orientated with your boat’s
current course facing the top of the screen. As your boat chang-
es heading, the on-screen boat symbol moves accordingly.
When a new course is selected, the chart redraws to show the
new course to the top of the screen.
Motion mode
Motion mode controls how your boat’s progress relative to the chart
is represented on screen.
To set the motion mode:
1. Press the PRESENTATION soft key.
2. Press the CHART MODE AND ORIENTATION soft key.
3. Press the MOTION MODE soft key to select your preferred
option.
