It remains unclear what exactly caused the incident but a father of one of the teenagers who survived the horrific incident said it was a rip tide that took them out .
The 78ft Dorset Belle was seized yesterday afternoon. The vessel, which operates hourly and can carry up to 80 people, is now under guard at Poole Harbour.
Lifeguards warned beachgoers of riptides before the tragedy at Bournemouth that saw a 17-year-old boy and 12-year-old girl killed, a boat passenger has today revealed.
The children were among ten people who were hurt after the shocking incident at a packed Dorset beach full of half term holidaymakers and locals yesterday afternoon.
