I learned this from Tom Riding, her owner.
Her mooring parted some few metres below the water on the same stormy late September day that saw a cruise ship break her moorings at Greenock Ocean Terminal, some 3 – 4 miles upstream from Gourock where Snow Star was moored. She (Snow Star) quickly crossed to the north bank of the Clyde and parked herself on a rocky shore close by Kilcreggan pier. By the time the salvage crew were able to get her off (a few days later) she was in a sorry mess on the starboard side, with a hole in the hull and sea water inside.
As I understand it, the insurance company settled and made arrangements for Snow Star to have a chance at a second life – hence she is for sale as a project boat.
I wish the best for everyone involved, and I feel for your loss, Tom.
