She reached Tristan da Cunha in 1953 where she was towed in by the islanders and was anchored near the shore. A few days later she went aground as what then was known as Big Beach,
During the volcano eruption in 1962 which covered Big Beach the yacht was covered in the lava and disappears completely.
