The ferry, which crosses the Strait of Juan de Fuca between Victoria and Port Angeles, Wash., crushed the dock as it backed out of its berth in front of the Regent Hotel around 7:30 p.m. PT Wednesday night.
Ryan Burles, the president of Black Ball Ferries, the company that runs the MV Coho, says it was unsafe to stop in the harbour, so the ferry continued on to Port Angeles.
Burles said the Coho Ferry captain is a 15-year veteran and the crew is very experienced.
"We've done this a lot obviously. We have a veteran crew, there was nobody new," he said.
"The vessel did not respond when it should have and that's the issue at this stage. Transport Canada, Harbour Control is there. We've contacted the U.S. Coast Guard."
Reports say it was windy at the time of the incident. There were no injuries and no boats or planes were damaged, but the seaplane dock is now shattered and floating upside down.
The 104-metre MV Coho, meanwhile, continues to chug in and out of the busy port today and has maintained its four scheduled crossings of the strait.
