SEATTLE – Firefighters responded to the 4400 Block of Lake Washington Blvd. S. just after 9:20 p.m. on Jan. 13 for a report of multiple boats on fire at Lakewood Moorage. When Engine 28 from the Rainier Valley Fire Station arrived on scene, they saw flames coming from the marina, with three vessels fully engulfed in flames.
Firefighters stretched nearly 2,000 feet of hose to reach the boats, and initially fought the fire primarily from land units. Once the Fireboat arrived on scene, water was applied on the fire from multiple angles. Due to quick and efficient firefighting efforts, the fire was knocked down in just over 20 minutes. 
Divers from Rescue One suited up, in case any rescues were needed. Firefighters untied and moved nearby boats, to prevent them from catching fire.
A boat owner and his dog were able to escape the fire, with assistance from Seattle Police Harbor Patrol and Seattle Fire. The approximately 59-year-old male patient was evaluated by Seattle Fire Department medics, and transported via AMR to the hospital with minor injuries. A Seattle Police Officer helped keep the displaced dog warm, while they waited for the owner to return.
Fire investigators responded to the scene and are actively investigating the cause. Further information will be released as it becomes available. Three vessels were a total loss.
UPDATE: Fire investigators have ruled the cause of the fire as undetermined. Total estimated loss is $200,000.
