The driver of a speedboat which killed two members of the same family as it raged out of control was not attached to a safety device designed to cut power in an emergency, investigators have said.
Nick Milligan, 51, the managing director of Sky's advertising sales division, Sky Media, was declared dead at the scene in Padstow, Cornwall, with his daughter, Emily, eight, following the incident on Sunday, May 5.
The Marine Accident Investigation Branch report states: "The [boat] was fitted with a kill cord, but this was not attached to the driver at the time of the accident.
"Consequently, when the driver was ejected from the boat, the kill cord did not operate to stop the engine and the [boat] continued to circle out of control, and at speed."
It said the boat ran over members of the family "a number of times" as it circled in the water.
A father of four who was killed in a speedboat accident along with his eight-year-old daughter doted on his family", his brother has said.
Two people have died and another four people have been injured in a speedboat accident while on holiday in Cornwall.
