Second vessel in two weeks appears to float above UK waters

Superior mirage' illusion resurfaces in Dorset a fortnight after similar pictures taken near Falmouth

If the sight of a ship apparently hovering above the sea is a very rare event in the UK, then two in a fortnight must be an even more unlikely occurrence.

But 13 days after a giant tanker was pictured floating above the water off Cornwall, the effect of an optical illusion known as a superior mirage, similar images emerged of the cruise ship, the Jewel of the Seas, off the Dorset coast.
