The Transportation Safety Board says human error is to blame, in part, after the BC Ferry "Coastal Inspiration" crashed into the berth at Duke Point in December of 2011.

The T-S-B says the team on the bridge didn't go by the book and didn't fully understand how to operate the "Inspiration's" propulsion system.

Bottom line: a malfunction in the controls went undetected until too late, and the ferry slammed into the dock.

BC Ferries has made a number of changes since, including regular response drills so everyone knows what to do. 

Seven passengers and nine crew members suffered minor injuries.

The ferry was out of action for 23 days
