Boat owner, Doug Schroedel lost everything in the fire.

He was trapped on the dock by the flames and had to use a dinghy to make it to safety.

Speaking to KSBW.com, he said: “Everything I need and of value is gone on the boat. I threw the latch thing open as quick as I could get out and was stuck on the end of the dock for 40 minute.”

Santa Cruz Fire Battalion Chief Jason Hajduk told the Santa Cruz Sentinel that the fire has caused approximately $500,000 in damage.

He said the fire broke out on one of the powerboats before spreading.

“Fibreglass burns incredibly well once it gets going,” he noted.

“We were focused on making sure everyone was safe and the fire did not spread to more boats or the dock itself,” added the fire chief.

Santa Cruz Yacht Harbor provides permanent moorage for approximately 1,200 wet-berthed and 275 dry-stored vessels.
