A Transportation Safety Board official says investigators have found "no systemic safety issues" after reviewing an incident in which a B.C. ferry got caught in violent seas last month.

Several cars were damaged and passengers were shaken in the early hours of Nov. 23 when the Northern Adventure got stranded in Hecate Strait while sailing from Prince Rupert to Skidegate on the Queen Charlotte Islands. The ferry eventually turned around and returned to Prince Rupert.

Ken Potter, TSB's manager of marine investigations, told ctvbc.ca Thursday that investigators interviewed the captain and reviewed the case, and determined that there was no need for a full-fledged investigation.

There were "no systemic safety issues arising from this incident," he said.

The marine forecast had called for winds to reach 40 to 60 knots and wave heights to reach at least five metres.

BC Ferries has said that the captain was aware of the storm but didn't expect it to hit so soon and with such ferocity.

Passengers have complained that the ferry should never have departed in the first place.
