Procedure
1 At the bottom of the display presentation, select a suitable presentation
mode, and activate the
Catch view.
2 To start the process: Press
Gear
on the Operating Panel.
or:
Right-click and select
Show Gear Symbol
on the shortcut menu.
This places a circle marker in the view. The size and location of the marker is defined
by the choices you have made with the
Fishing Gear
function. Until you proceed,
the marker follows the movements of the vessel by keeping its relative location to
the bow. This allows you to position your vessel in the best possible location before
you shoot the purse seine.
3 When you shoot the net: Press
Gear
on the Operating Panel.
or:
Right-click and select
Show Gear Symbol
on the shortcut menu.
A rectangular marker is placed in the view, and marks the position where the purse
seine was shot. The circular marker is disconnected from the vessel movements, and
acts as a guideline for your manoeuvring. The history line shows the movements of
your vessel. Since the ST90 system knows the length of your net, it places a second
marker on this line when half the length has been spent. When the entire net has been
spent, a third rectangular marker is shown.
The progress bar at the top of the Catch view shows you the amount of net that has
been spent. The sequence starts when you shoot the net. The estimated depth of the
purse seine is shown under the progress bar. The depth is calculated from the sink
rate you have defined for the fishing gear.
• Horizontal dotted lines show the depth intervals.
• Relevant information about a priority target can be found in the lower left corner of
the view.
A line of X’es in the vertical views shows the bottom of the purse seine. The depth is
defined for the fishing gear you have chosen.
4 When the process is finalized: Press
Gear
on the Operating Panel.
or:
Right-click and select
Remove Gear Symbol
on the shortcut menu to delete the markers
from the view.
