Hull with flat bottom
If the vessel's hull is flat you do not need a fairing. The
transducer is then be bolted directly to the hull using two bronze
or stainless steel bolts (I) and a cable bushing. Note that the
cable bushing must be mounted with proper gaskets (4) under
and over the hull, as well as sealing compound (J) around its
body. Also, fill the bolt holes with a filling compound to ensure
a smooth transducer surface.
