Ferry passengers were evacuated after their vessel crashed into a pier on the Kintyre peninsula.
A Maritime and Coastguard Agency (MCA) spokeswoman said 14 passengers were unhurt and disembarked safely after the ferry was reversed into the harbour at around 9.30am on Saturday.
The Caledonian MacBrayne ferry, the MV Isle of Arran, was also carrying commercial vehicles.
The ferry travels between Scotland's West coast and the islands of the Inner Hebrides.
The spokeswoman added: "It is now a case of assessing the damage to the vessel and the pier."
A Caledonian MacBrayne spokesman said: "I can confirm that it struck the pier and a full investigation is under way.
"Early indications are that it was due to a mechanical fault. Nobody was hurt."
Engineers are to assess the damage to the pier, which is not thought to be severe.
