This is the dramatic moment the Maid of the Loch paddle steamer slips back into Loch Lomond.
Workers were forced to jump out of the way yesterday as the 65-year-old ship broke free from her ties.
She was being raised inch by inch out of the water on her way to be restored when she suddenly slipped backwards.
No one was injured, but an investigation is now underway to establish exactly what went wrong.
The opertion was called off following the incident, and the Maid was taken back to her normal berth at Balloch Pier.
This video was captured by Bill Pentecost as he watched the scene unfold.
