Vertical coverage areas
When the seine is normally located forward of the starboard
beam when pursing the following information should be taken
into consideration:
The optimal tilt angle for dual
hydrophone installations is
derived in the same manner as a
for single hydrophone
installations. Consult the
section on Tilt angle for more
information.
The hydrophones should be
tilted so that the most important
part of the seine is adequately
covered. Tilting the forward
hydrophone -25_ and the after
-15_ will pr ovide proper
coverage in most instances.
Tilt should be no less than -15_ in most instances with the
optimal tilt angle depending on the size (length/depth) of the
seine in use.
Heeling of the vessel after the seine is set must be taken into
consideration when calculating the tilt angle.
