A boat fire, possibly caused by an on board heater according to a boat owner Stefan H. Krzeszowski in the same marina at Harbor Island, burned to the waterline after firefighters towed the boat into the Duwamish River and attempted to put the fire out. The fiberglass boat was fully engulfed and was a total loss.
A second boat was also lost and two other boats were damaged according to the Seattle Fire Department. The two boats sank as a result of the fire.

Krzeszowski said the first boat was approximately 32 feet in length. No word on the length of the other boat.

The dock is closed tonight pending further investigation.
