The UKC is the distance between the deepest point of the vessel's hull and the sea-
bed. The UKC feature continuously checks ship's draught setting (UKC), and actual 
depth. When the depth gets shallower than the UKC, the Alert 634 "UKC Limit" is gen-
erated. And if the current depth is less than the echo alarm setting the echo alarm also 
is generated. Depth data is required to use the UKC function.

Note: The sensor value shown is the depth to the transducer. Convert the value to the 
distance to the keel.

1. Select the [UKC] page from the [Overlay/NAV 

Tools] box.

2. Use [Echo Alarm Limit] to set the distance for 

the echo alarm. To activate the alarm, click the 
[ON/OFF] button to show [ON].

3. At [UKC Limit], set ship's UKC limit. To activate 

the UKC feature, click the [ON/OFF] button to 
show [ON].

4. Use [Current Draught] to set your ship's draft. 

Be sure to change the setting whenever the 
draft changes.

5. Use [Type] to set the shape of your ship's hull 

to show on the [UKC] window, [V-shape] or [Concave]. See the figure on the next 
page.
