Social media movies display black smoke billowing from a luxurious yacht on fireplace in St Tropez within the French Riviera on Thursday.
The blaze happened at the Sea Woman II, a 41m boat which sleeps as much as 10 visitors and can also be chartered from €65,000 (£56,000) every week.
Firefighters to start with struggled to get on board to comprise the fireplace, whilst emergency services and products briefly moved away surrounding yachts and publish anti-pollution limitations.
Officers stated the boat used to be more likely to sink within the port and the reason for the fireplace remains to be being investigated.
