Falmouth RNLI was helped by a person with a very small inflatable when rescuing a group stuck on mudflats near Tresillian on Thursday.
At just after 2pm the inshore lifeboat, along with Portscatho and Falmouth coastguard rescue teams, was sent to the mudflats below Penhale wood where two holidaymakers and a dog in a hired motor launch had been left high and dry.
There was not enough water for the lifeboat to come alongside, and the coastguard crews assembled at St Clements and started searching for an access point to carry out a mud rescue.
A coastguard spokesperson said: “Whilst this was going on, a member of the public with a very small inflatable proceeded to the stricken vessel and as he was able to get through the very shallow water, was able to get all of the casualties off.
"Once into deeper water, they were passed to the inshore lifeboat for transport back to Mylor where they had come from. All on board were safe and well.”
The holidaymakers were taken back to the boatyard in Mylor where they had hired the boat, and lifeboat crewmen told the yard where the boat had been left at anchor.
