lighthouse != all kind of physical navigation aids
Lightvessels, classical big lighthouses are obsolescence.
There are a lot of other physical navigation aids which are improved.
Old unlit marks are replaced with lit and AIS capable ones. New safe waterways and danger areas are marked every year.
Nobody said these are obsolete.
- Ekaros 4y agoLighted buoys and sector lights are still common and useful aids for navigation, both in dark and light. And you really don't some times go outside those specially with deeper drafts.
- sandworm101 4y ago>> classical big lighthouses are obsolescence. Nope. To see something in daylight it needs to be big. That big white pole is visible for miles and identifies the location in exactly the same way as the light does at night. Towers guided ships long before anyone started putting lights on them.
- sccxy 4y agoNope. For that there are daymarks. [1] Clover Island Light (2010) is the first lighthouse to be built in the United States since 1962. [2] If they are not obsolescence why they have built only one lighthouse in last 50 years in USA?
