Gear Symbol
The gear symbol is provided as a tool to help you plan and shoot the purse seine. The
symbol is intended to be used in a structured sequence that starts when you plan to shoot
the purse seine.
For use with a purse seine, the intended process follows:
1 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.
2 When you shoot the net:
• Press
Gear
on the Operating Panel. —
or:
• Right-click and select
Place Gear Symbol
on the shortcut menu.
The first timer starts when you select
Place Gear Symbol
.
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. In this phase the
Fishing Gear
function is disabled.
The first timer stops when the progress bar reads 100%. This action starts the second
timer, which stops when you select
Remove Gear Symbol
.
