The discussion focuses on the optical phenomenon observed in an image of a ship appearing to hover above the water, questioning the physics behind the gap between the ship and the sea. Participants explore the concept of mirages, particularly the Fata Morgana, suggesting that the ship's image may be a result of light refraction due to temperature gradients in the atmosphere. There is debate over whether the effect is a superior or inferior mirage, with some arguing that the color of the sea and sky may contribute to the illusion. The conversation highlights the complexities of light behavior and the rarity of such phenomena, emphasizing the need for a thorough understanding of atmospheric optics. Ultimately, the image raises intriguing questions about perception and the nature of mirages.

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.
