This fishing boat was about 10 kilometres away.

Air temperature on coast + 0.5 C

Air temperature 100 metres above sea about + 2 C

Sea temperature + 9 C

The effect was parallel (and had similar cause) to the shimmering seen above a tarmac road in summer: a very ‘hot’ surface with colder air above.

Nice one Jack, an inferior mirage over a relatively warm surface

with a rapid decrease of temperature with height.

The light to the observer is refracted (bent) .

A superior mirage with warm air above cold is the opposite as shown by the excellent photo taken by
David Morris off the coast of Cornwall.

I may be cynical but I'm not convinced that photo is what it claims to be.

I've seen similar things many times (well I do stare out to sea a lot!), when what appears to be the horizon is actually the limit of the sea breeze front. The real horizon far beyond in the haze. A bit of zoom to make the ship seem much closer than it is, & enhancement, that's what you get. It happens not infrequently.

Here's the reverse with no enhancement, approaching breeze.

If it was the reverse, with a ship on the horizon, a bit of zoom & enhancement and it's floating in space.

Here's 'my' boat in context.  South Sutor, Cromarty in the background.

Not sure what date the photo was taken off Cornwall or whether there was a sea breeze or not.
