A 12-year-old girl and a 17-year-old boy who died after being pulled from the sea off Bournemouth beach had “no physical contact” with a vessel on the water, police said.
Dorset Police said it was still “investigating the circumstances that caused a number of swimmers to get into difficulty” on Wednesday.
Eight other people were treated for non-life-threatening injuries.
A man in his 40s has been arrested on suspicion of manslaughter.
Emergency services were called to the beach, packed with people on half-term holidays, at 16:32 BST.
Dorset Police has released more information as officers work to piece together exactly what happened.
The force said it was working with partner agencies to understand what “caused the tragedy”.
“However, early investigation indicates that there was no physical contact between a vessel and any swimmers at the time of the incident,” it said in a statement released on Thursday.
Det Ch Supt Neil Corrigan also asked people not to speculate about the circumstances.

There are details the media have not yet been told about as the police try to piece together what happened.
But it was confirmed that the air ambulance landed on the beach on Wednesday afternoon, while a lifeguard attended on a jet ski in a bid to rescue those who were in the water.
The two children pulled from the water sustained critical injuries and died in hospital later. The other eight people who were rescued were treated on the beach.
The coastguard conducted a search to make sure no other people were missing and said it was “satisfied there are not”.
Police confirmed the man arrested was “on the water” at the time of the incident.
Some eyewitnesses told the BBC lifeguards began to tell people to clear the beach, saying there had been a major incident.
A section of the beach and the nearby Pier Approach were cleared and a cordon was put in place.

Tobias Ellwood, the Conservative MP for Bournemouth East, said protocols on the pier could be reviewed after the “terrible tragedy”.
He said Bournemouth prided itself on being a family resort and the incident had taken “everybody by shock”.
