A fire was reported at Dodson Marina in Stonington on Thursday morning.
Fire officials said four boats were on fire at the marina around 10:30 a.m. and were badly damaged by the flames.
No one was injured during the fire, officials said.
Connecticut Light & Power had to turn off the power in the marina, since there were live wires nearby.
The fire lasted about an hour, officials said.
It was unknown how the fires started.
