Three men have been rescued after drifting into shipping lanes on a jet ski in the Thames estuary off Kent.
The inshore lifeboat at Sheerness was launched at 17:40 BST on Saturday to help the men who were drifting off Allhallows, Isle of Grain.
Robin Castle, the RNLI's coxswain, said the propeller of the jet ski got tangled with a rope attached to an inflatable ring it was towing.
The men had drifted about a mile offshore on the outgoing tide.
The three men, aged 47, 21 and 18, were taken to hospital with mild hypothermia.
The 37-year-old and the 18-year-old are believed to be father and son from Strood, the RNLI said.
An RNLI spokesman said: "They could have been in deep deep trouble."
