Hunstanton lifeboat crews were called to help rescue a man after he fell from his boat into thick mud Thornham harbour.
Coastguard officials requested the launch of the station’s hovercraft at around 10.55pm on Wednesday night to help with the operation.
Several other emergency crews, including Wells Coastguard, Norfolk Fire Service and the East of England Ambulance Service, were also called to deal with the incident.
Lifeboat officials said that, on reaching the scene the crew received a radio message that the person had been pulled from the mud and was now in the care of paramedics.
The crew then returned to their station shortly before midnight.
A post on the Hunstanton Coastguard’s Facebook page said later: “Thankfully the person concerned, who was checked over by the Ambulance Service, was with someone who was able to raise the alarm.
“Otherwise it could have easily been a very different outcome.”
