Everyone knows that humpback whales are numerous during the migration season, and whales are known not to be aggressive against humans, but two holidaying sailors on their yacht off Fraser Island on Australia's Queensland coast hardly knew what to think when a whale grabbed their anchor rope in its mouth and dragged them out to sea.
Glenn Wilson and Nerida Higgins told Sky News they were enjoying a quiet evening moored in their yacht when the incident happened.
The frightening trip lasted 15 minutes as their boat was dragged 1.5 nm out to sea.
The couple called nearby boats, the coast guard and even police for help but all to no avail. None of the authorities would take them seriously.
'I don't think he believed me — I think they thought we'd had a few drinks of something,' Ms Higgins said.
When a second humpback whale took the rope in its mouth, the couple decided to cut the line, fearing their boat would get smashed up.
'We were hoping to see some whales but not actually that close,' Mr Wilson said.
The incident was captured on video by Ms Higgins, a bump in the night they will never forget.
