New Re: Radar.
On my river boat cruise down the Danube last October, I visited the boat's control room. One of things shown on the control room tour was the radar. They can see most anything substantial that floats. One of the things seen on radar was a group of three ducks ahead starboard. As this was daytime, they could be seen visually as well. This was reassuring as the boat did much of the sailing through the night.

I'll grant you this was relatively short range use of radar.

Are stories from legions long distance sailors struggling to remain visible to tankers, hoisting all manner of metal doodads aloft, and radioing vessels asking if they can be seen on radar only to be told "uh - wait - can you give me a bearing - oh yes - that must be you?"

Depends a lot on weather conditions. Waves hide things and produce noise for instance.
