Defects to windows on a Southampton-based cruise ship meant she was vulnerable when a large wave caused water to pour into cabins and injured those on board, a report suggested today.

The Oriana, operated by P&O, was travelling from New York to Southampton when she was struck by a wave, breaking six cabin windows and leaving those inside with cuts and bruises.

A report released by the Marine Accidents Investigation Branch (MAIB) found various defects with the windows had left them weaker than designed and possibly weaker than required by set standards.

The ship, carrying 800 crew and 1,500 passengers, was damaged after the wave, thought to be at least 10 metres high, hit the side during stormy conditions on September 28, 2000.

The report said that seven passengers and one crew member were in the cabins affected when the wave struck, leaving six of them with cuts from flying glass and bruises after being knocked over by the water.

A passenger in another cabin suffered shock after water poured on to her bed.
