The P&O ship got into difficulty after hitting a gangway while manoeuvring to leave port on its way to Dover.
Nobody was hurt in the accident though cross-channel traffic had been disrupted.
The crash came as Storm Ana batters the channel with 70 mph winds and it's believed the ferry ran aground after a huge gust caused it to lose control.
316 people, of which 208 passengers, were onboard the Pride of Kent ferry at the time.
The port of Calais has since been closed as a result of extreme weather.
