NET SHOOT

Net Diameter

Sets estimated ship's turn diameter necessary

PLAN

 

for shooting net, to get accurate depiction of

 

 

net location mark, which you can display by

 

 

pressing the NET COURSE key. The setting

 

 

range is 200 to 1000 meters in 10 meter steps.

 

 

 

 

Tilt Interlock

Choose ON to interlock diameter of net

 

 

location mark with tilt angle. When you lower

 

 

the tilt angle the on-screen net location mark

 

 

enlarges. (For example, the net diameter is set

 

 

for R meters. When the tilt angle is 45° the

 

 

diameter of the on-screen net is 2 R meters.)

 

 

 

NET SONDE

Net Sonde XMTR

Enter number of net sonde transmitters and

 

 

their distances between each other.

 

 

 

 

Net Length

Enter net length. The setting range is 500 to

 

 

3000 meters in 100 meter steps.

 

 

 

 

Wire Length

Enter wire length between own ship and net.

 

 

The setting range is 100 to 1000 meters in 100

 

 

meter steps.

 

 

 

 

Net Width

Enter net width. The setting range is 0 to 100

 

 

meters.

 

 

 

NET PLOT CORR

Layer 1

The movement of the net during net shooting

 

Layer 2

is plotted by using water current speed and

 

Layer 3

direction fed from external sensor. The

 

 

external sensor feeds that data for three depths

 

 

(layers), thus net movement will be different

 

 

at each layer. Determine degree of difference

 

 

among layers considering net, sea conditions,

 

 

vessel construction, etc. If 50% is set, for

 

 

example, on-screen net moves at speed of

 

 

50% of water current speed.
