Measuring the Potential Front-of-Boat Offset

The front-of-boat offset compensates for the physical location of the radar scanner on a boat, if the radar scanner does not align with the bow-stern axis.

  1. Using a magnetic compass, take an optical bearing of a stationary target located within viewable range.
  2. Measure the target bearing on the radar.
  3. If the bearing deviation is more than +/- 1°, set the front-of-boat offset.
