Burglars have been raiding yachts and houseboats in the Oakland-Alameda Estuary in a surge one resident compared to the pirate movie "Captain Phillips." They steal anything of value, then either sink the ships or dump the remnants of plundered boats miles away in the Oakland Harbor or along its shorelines, said Dan Hill, who lives on his boat like many other families in the 800-foot waterway. Each "attack" can cost the owner thousands to tens of thousands of dollars, Hill said.
