SAN FRANCISCO (KGO) --Fire boats played a large role in saving the marina from a fire after the 1989 Loma Prieta earthquake.

On Monday, the city introduced its third boat at McCovey Cove for the official commissioning ceremony for the Saint Francis.
The boat cost nearly $12 million. Most of the money came from a port security grant.
Fire officials showed off its impressive firefighting cannons and apparatus.
The Loma Prieta earthquake was on Senator Dianne Feinstein's mind. She recalled how a fireboat fed a portable hydrant to help stop the marina fire in 19-89.

"I was told all the water mains were out," she said. "So that hydrant went up Divisadero Street, and actually to a great extent saved the day."
The Saint Francis joins the Phoenix and the Guardian in the department's fleet.
The son of a San Francisco firefighter won a contest to name it.
