Firefighters responded to a boat fire on Fort Myers Beach near the Pink Shell Marina Thursday night.

The U.S. Coast Guard towed the boat to Bowditch Beach where firefighters boarded the vessel and extinguished the flames.
No injuries were reported.
Sanibel Fire Rescue District said fires that occur on boats can spread quickly and have unique challenges due to hazardous conditions and limited access.

Seven crew members of a commercial fishing boat were rescued after their boat caught fire Wednesday off the coast of Monterey, the Coast Guard said.
Watchstanders with the Eleventh Coast Guard District command center in Alameda received multiple alerts belonging to the fishing boat Blue Dragon around 12:20 a.m and arranged for a Coast Guard Air Station Sacramento C-27 Spartan aircrew to fly over the area about 350 miles (563 kilometers) west of Monterey
Coast Guard watchstanders also issued a request for assistance and the vessel Nord Rubicon crew responded that they were willing to divert and assist the distressed mariners.
The C-27 aircrew reached the area about three hours after the Coast Guard received the distress alerts and reported seeing the Blue Dragon on fire and survivors aboard a life raft nearby. The survivors signaled the aircraft using a flashlight, and in response, the aircrew deployed a flare along with a self-locating datum marker buoy.
The Nord Rubicon crew arrived on the scene at 9:30 a.m. and rescued the seven crewmembers from the life raft. No injuries were reported.
The Nord Rubicon was en route to San Francisco with all Blue Dragon crew members, officials said.

A boat caught fire Tuesday morning on the Indiana side of the Ohio River.
The first calls of a possible boat fire came in around 8:30 a.m. near Rising Sun in Ohio County. The fire happened near the 499 mile marker on the Ohio River.
The fire was still burning at 1:30 p.m., when officials said they've stopped putting water on the fire out of fear the additional water could cause the boat to sink. The tug boat also carries 35,000 gallons of fuel and officials said they fear the river could be contaminated if too much water is poured on it.

The Coast Guard led the fight with the fire, alongside with several local fire departments.
Officials have not said whether anyone was injured in the fire, but employees on the boat did evacuate.
