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 SU90 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 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.
