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.

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:
