Remember
: aligning the radar with a chart is not a perfect science. Remember that a chart
is a hydrographers artistic view of the coastline and surrounding navigable information. A
radar on the other hand is a real depiction of what is being returned and interpreted by the
radar. You should expect that there will be some level of disparity between the chart and the
radar.
Adjusting the Compass Master Heading Correction
This process allows you to align the digital compass with the vessel center line. This
is normally a one-time process that corrects the entire 360° equally.
To align the compass
1. Start the Nobeltec Navigation Software and open a chart window where you can see the
icon that represents the boat.
2. Right click the boat and select
Properties
from the menu.

3. When the Boat properties window is open, the
General
tab shows how the compass
bearings are displayed (True or Magnetic) along with the magnetic variation at the boat
location. Click the
Deviation
button to open the
Compass Heading Corrections
window.
4. Determine the amount of offset and enter it in the Compass Heading Correction window.
