Police said the 11-year-old died yesterday at West Middlesex Hospital after she was seriously hurt at the Princes Club in Bedfont, about 29km west of London.
It was understood that the girl, named by the club as Marie-Simone Cronje, was on an inflatable and being towed by a boat when she fell off and was struck by the same vessel, Sky News said.
"Princes Sporting Club and everyone associated with it is devastated by the accident. At this terrible time, our thoughts and deepest sympathies are with Marie-Simone Cronje's family and friends," the centre said in a statement.
An autopsy will be carried out, a spokesman for London's Metropolitan Police said
