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.
