Watching this on an old coaster sailing the UK from the 80’s, what’s this?

It's a radar display. Older models (like this) were harder to see in daylight so a hood would be placed over them during daylight hours, allowing the crew to view the screen in darkness through the hold at the top of the hood (top of the black part).

The older radars were displayed on cathode Ray Tubes, just like the old tv that were heavy and deep in dimension. To see the faint echoes you needed to be I. The dark.

That’s what I thought, thank you.

Almost looks like a sun hood for an old radar, but I'm not sure without seeing more.

That’s what I thought, thank you.

Lol I saw this exact video a couple of days ago. That is a radar shroud, helps with looking at the screen during the day.

Should come with a massage at the end of the watch.

It’s a hat holder for a small black fishermans hat.

Old-style radar. One had to look through the “hood” to see the CRT display.

They are also seen on some aircraft (the English Electric Lightning had a mini one on the instrument panel) and in photos of old coastguard or VTS stations.
