I'm pretty sure this is not the type of mirage you linked (which would be above the real horizon) but rather one that is below the real horizon. That is, the ship is seen above the real horizon, but the water near the horizon is hidden by a mirage of the sky. You can faintly make out the real horizon, as well.

Not an expert but I think you're right. The Wikipedia page OP linked describes the phenomenon this way:

Fata Morgana mirages significantly distort the object or objects on which they are based, often such that the object is completely unrecognizable... The mirage comprises several inverted (upside down) and upright images stacked on top of one another. Fata Morgana mirages also show alternating compressed and stretched zones.

They include a pretty good example with a container ship:

I think that's just shadows, but I could be wrong. It's some type of superior mirage. Title edited for accuracy.
