ALAMEDA -- Firefighters have contained a fire aboard a boat docked in the Oakland-Alameda estuary that sent a plume of black smoke billowing into the sky on Wednesday afternoon.
No one was aboard the boat at the Fortman Marina on Buena Vista Avenue, where the fire broke out about lunch time.
The live-aboard boat measures about 35 feet long and was gutted by the blaze, Interim Fire Chief Mike Fisher said.
What sparked the fire remains under investigation, Fisher said. A witness said she thought it may have began when a propane tank exploded.
Billowing smoke from the fire could be seen across the Island and in Oakland.
Fisher said he did not have a financial estimate for the damage the fire caused to the boat and its contents.
No other boats or structures were affected by the fire.
Alameda firefighters initially dispatched three fire engines, two fire trucks and an ambulance. An additional engine was dispatched after the first firefighters arrived at the 497-berth marina, which is near the former Del Monte warehouse on Buena Vista Avenue.
