The existance of rogue waves is proven commonplace

The presence of rogue waves of 100 feet was thought to be a myth until now.

As part of a project called MaxWave - which was set up to test the rumours - two Esa satellites surveyed the oceans.

During a three week period they detected 10 giant waves, all of which were over 25m (81ft) high.
