A group of young sailors have described how panic set in when a killer whale started smashing into their yacht - before they fought the huge beast off using vinegar.
The 20-year-old women, from Norway, were on board the sail boat Nova Vida passing Lisbon, Portugal, on their way to the fishing town of Sines when the killer whale attacked on September 13.
Shocking video shared with the Daily Mail shows the vessel jolting and its steering wheels spinning out of control as the orca repeatedly rammed the hull.
Elise Wurschmidt, who was on a day trip with two friends and their captain, said: 'We turned on the engine and some minutes later, the wheel just starts to spin uncontrolled.
'We figured something might be wrong and then on the side of the boat we could just see a huge orca.'
