Why are lighthouses still necessary?

1.47K views

With GPS systems and other geographical technology being as sophisticated as it now is, do lighthouses still serve an integral purpose? Are they more now just in case the captain/crew lapses on the monitoring of navigation systems? Obviously lighthouses are more immediate and I guess tangible, but do they still fulfil a purpose beyond mitigating basic human error?

Look up the coastline of Maine on a map. There’s a reason Maine and New England are known for lighthouses. There are a lot of islands and the underwater topography is chaotic. Lighthouses serve a very needed function.
