A Mayday call was made to coastguards when a motor cruiser spotted the capsized vessel and three-man crew in water.
Three people had to be rescued when a boat selling ice cream capsized.
The Lolly Roger is believed to have overturned when a freezer containing ice cream rolled while on board.
A Mayday call was made to coastguards when a motor cruiser spotted the capsized vessel and three-man crew in water off Hengistbury Head in Dorset.
The motor cruiser, Badgers Retreat, picked up the three people and took them to Mudeford Quay, where they were met by Southbourne coastguard rescue team.
A spokeswoman for the Maritime and Coastguard Agency said the coastguard search and rescue helicopter from Portland was scrambled but stood down as it was not required.
She said: “Mudeford inshore lifeboat towed the capsized vessel into Mudeford Quay where it was later inspected by a Maritime and Coastguard Agency surveyor.
“A prohibition notice has been served on the vessel as equipment used on board makes the vessel unsafe. It’s believed the freezer on board shifted position, which in turn capsized the vessel.”
The three casualties, a woman and two men, were not seriously injured.
