Claim 10:
11. An electronic system for use in connection with navigating a marine vessel to a desired position along a waterline boundary:
a display;
a light detection ranging (“LIDAR”) sensing system configured to detect structure in a region by vertically scanning the region, the structure comprising the waterline boundary;
a memory element configured to store characteristics of the detected structure;
a processing element coupled with the LIDAR sensing system and the memory element, the processing element configured to:
determine, and store in the memory element, a characteristic of the detected structure,
identify a primary reference point associated with navigation of the marine vessel to the desired position based on the determined characteristic of the detected structure,
control the display to present information related to a current position of the marine vessel in relation to the identified primary reference point and the desired position along the waterline boundary,
identify a secondary reference point having a linear correlation to the primary reference point, and
continually determine a distance between the primary and secondary reference points;

wherein, if differences in subsequent measurements of the primary reference point exceed a variability threshold, the processing element uses the secondary reference point for navigation based on the previously determined distance between the primary and secondary reference points.
