The Illusion of Anti-Gravity (aka a Superior Mirage)

[DrStupid]

I think it is still puzzling why there was insufficient warning from the watch.

I think it's not that puzzling with the stars as the only source of light.

Dark adapted from parapet on a crystal clear night with low swell I would think one should be able to see an iceberg ahead using only starlight, absent these aberrations. I am interested in the opinion of the several good sailors amongst us.

Isn't this the same effect that some folks think sunk HMS Titanic?

HMS is reserved for warships of the Royal Navy.

I'd need to check Titanic but it would have been SS (steamship) or RMS (Royal Mail Ship).

Regarding the photo, it looks like the British have resorted to innovative tactics to beat the post-Brexit trade tarriffs.
