Using Mariner’s Eye
Mariner’s Eye provides a view from above and behind the boat (according to your course), and
provides a visual navigation aid. This view is helpful when navigating tricky shoals, reefs, bridges,
or channels, and is beneficial when trying to identify entry and exit routes in unfamiliar harbors or
anchorages.
