Y Offset
Select the offset value on the Y axis (athwartship) from the default
Ship Origin
. This
is the origin that was defined by the vessel designer and/or the shipyard when the
vessel was built. Adjust with a positive value for Y if your new preferred origin is
located on the starboard side of the default
Ship Origin
.
Z Offset
Select the offset value on the Z axis (vertical) from the default
Ship Origin
. This is
the origin that was defined by the vessel designer and/or the shipyard when the vessel
was built. Adjust with a positive value for Z if the new preferred origin is located
under the default
Ship Origin
.
Ship Dimensions
Insert the physical dimensions of your vessel (length and width).
Do this as accurately as possible. This information is used to create a new origin
in the vessel coordinate system.

Transducer page
Use the
Transducer
page to define the physical location of the transducer in the vessel
coordinate system, as well as the installation angles (rotation). The installation angles define
in which direction the transducer face points.
Description
The physical location of the transducer is important for the echo data accuracy.
Use the centre of the transducer face as reference, and define the offset values related to
the
Ship Origin
. The installation angles relevant for the transducer must also be defined.
These values were recorded during the installation, and they define the direction of the
transducer face.
Note
It is very important that the transducer installation angles are measured and recorded
accurately during the installation. Incorrect angles will greatly reduce the data accuracy.
