Watch in amazement or, indeed, terror as this video clip captures the moment a cruise ship is hit by a series of heavy waves at sea.
The footage from LiveLeak.com is supposedly taken from CCTV on-board the Pacific Sun, a vessel belonging to P&O Cruises, and shows the effect of the wave at various points around the ship.
There is no detail as to when the footage was obtained, but could relate to a famous incident in the summer of 2008 concerning the Pacific Sun.
The startling footage shows the efforts of staff to keep passengers upright, an action which looks bizarre as the locked camera cannot illustrate the extent of the angles the ship is leaning.
