A disconnected cable resulted in the master being unable to put the engine into neutral or astern from ahead and a subsequent hard contact with the jetty at Nybrokajen says the Swedish Transport Agency. Some 24 passengers one injured, including one broken collarbone.
Why the cable disconnected is unknown and no disconnection alarm was fitted. A casual observation would not have revealed the problem because of the cable covering. The incident does highlight the need to initiate critical manouevres with enough time to take appropriate action.
