Liz Richards (65) and Sarah Usher (34) desperately climb back onboard. The Storm is evident in the left hand side of the image.
This is the heart-stopping moment two British sailors are washed off the side of a yacht as it is knocked flat by a tornado in the middle of the ocean.
Sarah Usher and Liz Richards are seen desperately trying to grab hold of the 70ft boat as they are swept overboard when the freak weather conditions hit.
Their 70ft yacht was blown onto one side as the wind built then smashed almost 180 degrees onto the other as the tornado struck.
Winds of more than 115mph pinned the capsized yacht down for around 60 seconds.
Dramatic footage of the ordeal shows the boat's crew dragging the pair out of the water and back on board the boat as the winds ease.
The tornado can then be seen disappearing into the distance as the boat returns to upright.
Sarah, 34, from Hull, East Yorks, and Liz, 65, from Dartmouth, Devon, were both wearing life jackets at the time and were shaken but uninjured in the ordeal.
They were part of an 18-strong crew on the Great Britain yacht competing in the Clipper Round the World Race, a 40,000-mile yacht race for amateur sailors.
