Figure 4
Recommended location of the transducer array on the hull
The possibility of getting air bubbles in front of the transducer array is the most
important factor.
Figure 5
Transducer array located on a bulbous bow
If a nominal horizontal mounting of the transducer array is desired, the transducers can
be mounted parallel to the keel. Most ships have a positive design pitch of 0.5 to 2°.
Backward tilt is not recommended, it may limit the operational weather window.
The recommended transducer array location is in the fore part of the hull, and normally
follow the keel line with respect to tilt.
