SEATTLE - Seattle fire investigators are trying to figure out what started a three alarm fire onboard a commercial fishing boat.
The fire broke out around 2 a.m. In the 1300 block of West Nickerson Street, along the Ship Canal.
Firefighters say the vessel involved is the 100-foot "Arctic Dawn," which was featured in the first seasons of the Discovery Channel's "The Deadliest Catch."
One person was onboard but got off safely.
A hundred firefighters attacked the fire from the ground and water.
"Certainly any ship fire is a challenge. The biggest challenge right off the bat is just access," said Seattle Fire Dept. spokeswoman Dana Vander Houwen.
Crews were able to keep the fire from spreading to neighboring boats.
No injuries were reported.
The Coast Guard and Department of Ecology is on scene, but fire officials say it doesn't look like any fuel spilled.
