Context
Use the information in the Catch view to monitor the progress of the purse seine
operation. If you have connected a compatible catch monitoring system to your SN90,
information from these sensors are shown in the
Catch view.
Procedure
1 At the bottom of the SN90 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 SN90 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 object 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.
