The report into the tragic death of a schoolgirl at a west London water sports club has said it's safety procedures were flawed at every level.

Mari-Simon Cronje, 11, of Putney, died on September 11 last year when she was hit by a ski boat after being flung off a banana boat into the water at the Princes Club Water Sports Park in Bedfont, Middlesex.

An investigation by the Maritime Accident Investigation Branch (MAIB) said the 22-year-old male driver of the ski boat towing the inflatable had not seen her fall off.

When he continued the boat on it's tight circular route, it ran over Mari-Simon and the propeller struck her, causing several injuries and massive blood loss.

She was rushed to Isleworth's West Middlesex Hospital but was pronounced dead shortly after arriving. The post-mortem examination found she had died of severe leg and perineal injuries.

The report, released on July 20, said: "The implementation and execution of the safety management system used at Princes Club was flawed at every level and had not identified or controlled the risks to children taking part in banana boat rides effectively."

A number of safety issues that could have contributed to the accident were identified including the fact an observer was not present on the boat to see if anyone had fallen off, meaning the driver had to divide his attention between looking ahead and checking if the banana boat riders were ok.

It was also said the protective grey helmet Mari-Simon was wearing difficult for the driver to see.

As a result of her death, the club has taken a number of significant steps to address the shortfalls of it's safety procedures.

It now does not offer towed inflatable rides and puts it's drivers through advanced training as well as having employed a new company of health and safety advisers.

A statement from the club in response to the report said: "First and foremost, we want to make clear that our thoughts and sympathies are with the family of Mari Simon-Cronje. We are acutely aware that there is little that we can say that can be of any comfort at this time.

"Princes Sporting Club has been operating for 50 years and has previously maintained an excellent health and safety record and has never before been the subject of a prior investigation or prosecution.

"We are co-operating fully and openly with all the investigations being carried out into this accident."

A Metropolitan Police spokesman confirmed the driver was arrested in connection with the incident and is on bail pending further enquiries He is due to return for questioning in October.
