Figure 2 General recommendation for transducer location

Summary and general recommendations
Some of the above guide lines are conflicting, and each case has
to be treated individually in order to find the best compromise.
Generally the propeller noise is the dominant factor, and a
recommended transducer location is in the fore part of the hull,
with maximum distance from the bow equal to one third of the
total length of the hull at the water line.

Maximum 1/3 of the hull length at water line (C)

If the vessel hull has a bulbous bow, this may well be a good
transducer location, but also here must be taken into consideration
the flow pattern of the aerated water. Often the foremost part
of the bulb is preferable.
