The fire started around after midnight on the Indonesian holiday island and quickly engulfed nearly 40 local vessels but no injuries were reported, police said.
"So far there are no casualties," Bali police spokesman Hengky Widjaja told AFP.

Firefighters were still trying to put out the blaze by mid-morning.
Crew member Supriyanto, who goes by one name, said he had been asleep on his vessel when he awoke to see the upper part of the boat on fire.
The blaze quickly spread to nearby vessels including small cargo ships, he added.
Several witnesses said they suspected the fire was started by an electrical malfunction, but authorities said they were still investigating the cause.
Accidental blazes are common in Indonesia where fire safety regulations are often ignored.
