Radar advances
Ocean Navigator|September - October 2020
Marine electronics companies continue to make impressive technical strides in a variety of areas.
Radar advances

One of these is radar. The marine radar units currently available to voyagers have impressive capabilities — in particular, their collision avoidance options that make voyaging easier and safer.

The recent World War IIera movie Greyhound starring Tom Hanks depicts the Battle of the Atlantic and has radar as a major element. We see the crew of Hanks’ destroyer using radar to detect enemy submarines. The radar of that era was good for detection and ranging, but in order to know anything about how a particular vessel was moving relative to your own, you needed to break out the grease pencil and plotting board to manually draw in the bearings and vectors. The filmmakers of Greyhound actually give us a quick example of this process, and we see a crewmember calculating a course to intercept by drawing grease pencil lines on a erasable plotting board.

For commercial mariners in the immediate post-WWII era, radar sets were developed with special plotting screens that overlaid the radar display.
