According to the Marine Traffic website, the vessel docked at Bournemouth Pier before the first 999 calls.
Searches continued on the Bournemouth touring boat where a teenager and newborn died.
Police impounded the boat after Wednesday’s rescue of a 12-year-old Buckinghamshire girl and a 17-year-old Southampton boy.
Eight additional patients were treated by paramedics.
The Dorset Belle was guarded by a police vehicle at Cobb’s Quay in Poole Harbour on Friday.
On Thursday, a 40-year-old guy “on the water” was arrested for manslaughter and released awaiting further inquiry.
According to the website Marine Traffic, the boat visited Bournemouth Pier, the location of the incident, at 4:00 p.m., just minutes before the first 999 calls were made, and then returned.
The swimmers did not jump from the pier, according to police.
Bournemouth, Christchurch, and Poole Council (BCP) stated that it had not issued a license for the Dorset Belle and that the Maritime and Coastguard Agency (MCA) was responsible for licensing vessels of this scale.
The police will not comment on the boat probe or whether a vessel was involved.
Tobias Ellwood, Conservative Member of Parliament for Bournemouth East, opined that police should provide additional information to prevent “wild speculation.”
He added, “The police are conducting their investigation, and there must be a review of the circumstances to determine whether any safety measures and protocols need to be upgraded to prevent a recurrence.”
The boat’s website says it was designed for “occasionally challenging swell conditions encountered at local piers.”
According to the council’s website, yellow buoys are placed 200m from the low water mark from April to October to indicate that watercraft must not “exceed six knots, annoy or endanger other beach users, run ashore or launch from the beach, or run aground or launch from the beach.”
Councilwoman Vicky Slade stated, “There is no evidence that any of these rules were violated.”
Together with our collaborators, we are confident that any future lessons to be learned will be learned.
Dorset Police are also investigating the incident alongside the Marine Accident Investigation Branch and the Maritime and Coastguard Agency.
