Floating dock at East Boston shipyard plunges into water too fast, right into a boat

Rigging on a crane being used to lower a floating dock or "barge" into the water at the Boston Harbor Shipyard and Marina, 256 Marginal St. in East Boston, failed at 11:08 a.m., sending the dock slamming into the water - and a boat that happened to be in the wrong place at the wrong time, the Boston Fire Department and the shipyard report.

Nobody was injured, but the shipyard reports it shut for the day, to await a second crane to help right things.
