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