Fire Marshal Erik Guevin says the boat, used for tours of the lake, is moored at Zephyr Cove, where fire broke out shortly before 8AM August 16, 2016.
Flames extensively damaged an upper deck. A crew was on board doing renovation work, including welding. It was members of that crew who were hurt.
There is no word yet on the cause. The Coast Guard is conducting the investigation. The boat is reportedly structurally sound, but in no shape to carry passengers until repairs are done. The vessel is also holding water from the firefight and is listing slightly as a result.
Sister ship the MS Dixie was moored next to the Queen, but was not damaged.
