Defining the athwartships location of the hull unit
The athwartships position is not critical. The hull unit may be located on the Centre Line
(CL) of the vessel, or alongside its keel.
Note
If the installation is offset from the vessel’s centre line, make sure that transducer
transmissions and reception will not be obstructed by the keel.

Installation with more than one hull unit
You may need to install the MF90 hull unit aft of an existing hull unit. If these hull units
are placed one after the other along the keel, you must make sure that you have sufficient
distance between them.
A
Outer diameter of installation trunk
B When mounted in the longitudinal
direction of the hull, the distance
between two installation trunks
must be minimum three -3- times
the diameter of the forward trunk.

Note
When mounted in the longitudinal
direction of the hull, the distance
between two installation trunks must be minimum three -3- times the diameter of the
forward trunk. This is important to increase performance and to reduce noise and excessive
vibrations that can damage the hull unit.
