A fire broke out on a day-trip boat in the harbour of the popular small Greek island of Paxos, with the flames quickly spreading to a second vessel moored nearby, local media reported on Thursday.
The passengers, the majority of them tourists, had disembarked shortly before the fire broke out.
The blaze spread rapidly, triggering a large response from authorities and the fire service, online news services from the neighbouring island of Corfu reported.
The coastguard said there were no immediate reports of injuries.
The cause of the fire remained unclear. Port authorities have opened an investigation.
