A fairing, made by the shipyard, is placed between the
transducer and the hull, to adapt for the deadrise angle of the
hull. The fairing can be made of wood or steel, and should have
the same outline dimensions as the transducer. These
transducers are mainly used on smaller vessels. A location
approximately 0.5 m aside from the keel may be adequate for
the passage of water between the keel and the transducer. The
figures above and below illustrate external mounting of
transducers on steel hulls and on wood or polyester hulls
respectively.
Refer to figure 19 and 20.
