One of two people injured when a Golden Gate Ferry and a 22-foot motorboat collided in the San Francisco Bay on Saturday has died, a U.S. Coast Guard spokesman said Monday.

The victim was identified as 68-year-old Harry Holzhauer, of Tigard, Ore., Coast Guard Lt. j.g. Mark Leahey said.

The crash happened at about 4 p.m. in Raccoon Strait, near Tiburon. The Coast Guard is still investigating the circumstances of the crash and who was at fault, Leahey said.

Golden Gate Transit spokeswoman Mary Currie said the motorboat was traveling at a high speed when it collided with the MS San Francisco, which was about 10 minutes into its 30-minute trip from Sausalito to the Ferry Building in San Francisco. 

Holzhauer and another man on the motorboat were injured, but none of the roughly 500 people on the ferry were hurt.

Leahey did not have an update on the condition of the second man who was injured.

After the collision, the ferry continued to San Francisco, then returned to Sausalito where it was taken out of service.

Currie said the five crew members aboard the ferry were drug tested and placed on administrative leave, as is protocol with such incidents.

She said Monday that the crew members have all returned to work except for the captain, who remains on administrative leave.

The ferry was examined by the Coast Guard after the crash and was back in service Monday on the Sausalito-to-San Francisco route, she said.
