Both Falmouth lifeboats were launched on Saturday to assist a boat that had run aground in St Just Creek.
The lifeboats were called by Falmouth Coastguard just after 2pm to help the 45ft ketch Lily of Laguna, which had grounded with two people on board.
Falmouth RNLI said: "Due to the state of the tide and the location of the vessel the all weather lifeboat stood off while the inshore lifeboat checked the stability of the boat before laying out two anchors.
"Once this had been completed the crew were taken off the boat and dropped ashore."
The Lily of Laguna was built in 1927 and worked as a pleasure launch in the Isles of Scilly for many years transporting people between the islands. In 2002 she left the islands for Falmouth where she has undergone an extensive conversion into a ketch.
The all weather lifeboat crew were: Mark Pollard (Coxswain), Alistair Heane, Andy Jenkin, Sandy Procter, Neil Capper, Jonathan Jeeves, Jack Chuter
The inshore lifeboat crew were: Diane Bush (Helmsman), Tom Bird, Derren Plaister
