Using Mariner’s Eye 3D
Mariner’s Eye 3D provides a bird’s eye 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.
