A stricken yacht sent out a desperate Mayday call on Saturday (September 13) in Dartford.
The Gravesend RNLI launched a lifeboat at the request of the London Coastguard after the yacht ran into trouble on the Thames in Long Reach, near the QE2 Bridge at around 3.30pm.
The yacht issued the distress signal after it experienced engine trouble and struggled against the tide.
After the RNLI lifeboat arrived a crew member boarded the yacht and decided, with London Coastguard, to bring the boat back to its mooring at Thurrock Yacht Club in Essex and the owner remained on board.
The Mayday signal originates from the French phrase, 'm'aidez', meaning 'help me'.
A senior radio officer Frederick Stanley Mockford developed the call in 1923 at the now defunct Croydon Airport.
