6.2 Heading Adjustment
When the BOW mark on the flange of the hull unit cannot be directed toward ship’s bow adjust the heading so an echo which is dead ahead appears dead ahead on the display.
1.Locate a target in the bow direction (buoy, for example) and display it on a near range. If the target appears at 12 o’clock the heading alignment is correct. If it does not go to step 2.

If target's
position is right of ship's bow, hull unit heading
is skewed to left.
