Rangers spotted thick black smoke issuing from the stern upper deck on the USS Cassin Young, a World War II destroyer, around 10 p.m. on December 30th. An engine from Boston FD responded; upon seeing the thick black smoke, firefighters summoned additional support. At least three ladder trucks, four engines, two EMS vehicles, four Boston FD SUVâs, two Boston PD cruisers, and three boats â one each from Boston FD, Boston PD and the Coast Guard â all responded. Firefighters sprayed about 200 gallons of water on the area of the ship from which the smoke was emanating and knocked down the fire. The smoke was found to be issuing from the boiler room. Boston FD investigators and NPS personnel determined that one of the boilers had failed due to age and was the cause of the smoke. The damage has been estimated at about $25,000. The USS Constitution, berthed nearby, was not affected. To see a short news video of the response, click on the link below.
