Careening Bay was named by Lieutenant Phillip Parker King after his ship, HMC Mermaid, was careened there during his third voyage of discovery in 1820. King surveyed the western coast to complete the map initiated by Flinders 20 years earlier. The Mermaid had been leaking badly and King needed to find a shallow sandy bay where he could careen his boat to undertake repairs. At a high tide, on a warm September afternoon, he ran the Mermaid onto the sands. For ten days the Mermaid crew worked hard before refloating the vessel. The ship’s carpenter carved the name of the vessel and the year into a conspicuous boab tree. The famous boab tree is now 3 metres wide and National Heritage listed. A reminder of a by gone era of exploration!
