Simrad ES70
Example: Streamlined transducer on wooden or polyester hull
A fairing (A), made by the shipyard, is placed between the transducer and the hull. It is
required in order to adapt for the deadrise angle of the hull, and will also house a cable
service loop (B). The fairing is made from wood, polyester or steel, and should have the
same outline dimensions as the transducer. Use tarred felt (H) between the fairing and
the hull. Remember to create an air outlet (E) on the fairing, and to fill the bolt holes
with a filling compound to ensure a smooth transducer surface.
