No one was injured in a fire that destroyed a boat Tuesday morning at the Deception Pass Marina, in Cornet Bay.

At 8:47 a.m., North Whidbey Fire and Rescue was called to respond to a burning 34-foot Bayliner that was built in 1986, according to Chief Chris Swiger. The cause of the fire is unknown and will be listed as “undetermined,” he said. There were no passengers on board.

The vessel, which was secured to a dock, burned for over an hour as North Whidbey firefighters tamed the flames assisted by the Mount Erie Fire Department, NAS Whidbey Island Fire Station 71 and boats from the Swinomish Fisheries Patrol, the Skagit County Sheriff and the Everett Fire Department.

The boat sank and was left sitting semi-submerged in the bay as it awaits to be towed away, Swiger said.

The effort was particularly challenging because the boat was on the water, Swiger said, giving firefighters limited space to move around. Firefighters also can’t wear life jackets due to their flammability, but the self-containing breathing apparatus can help them float for a short amount of time in case they accidentally fall in the water, he said.

A few nearby boats were scorched, though they showed minimal damage. Had the boat been under the boathouse, he said, the situation could have turned into a “disaster.”
