Pictures streamed into our FOX 11 ReportIt feature, around 7 p.m., shortly after the fire broke out.
Three boats were destroyed by the fire.
Crews worked overnight to clean up the damage left by the fire at Skipper Bud's Quarterdeck Marina in Sturgeon Bay. Crews also stayed to make sure the fire did not flare back up.
Firefighters say three fiberglass boats docked close together burned Monday night.
The cause is under investigation. The Door County Sheriff's Department says it is still too early to tell where, or how, the fire started.
FOX 11's Gabrielle Mays will have more on this story tonight on FOX 11 News at Five.
