Hull unit installation example: Side view (off keel/with blister)
The hull unit is located in the sonar room. This example shows a typical sonar room and hull unit seen from the side. The hull unit is mounted on the side of the keel. A blister is added for streamlining and protection.

D Access hatch

F Mechanical support brackets (Due to its height and weight, the hull unit gantry must be secured to the bulkhead by means of mechanical support brackets.)
G Transceiver Unit
H Heater
I Strengthening knee plates (stiffereners)
J Streamlined blister
The streamlined blister is an option. The blister may work well on smaller vessels. This is because it allows you to bring the installation trunk and hull unit down closer to the keel. A lower position will increase the depth of the transducer relative to the hull.
