SS Violet
From Super-wiki
Sam refers to the SS Violet as an example of a Ghost Ship in 3.06 Red Sky At Morning.
The S.S. Violet, a paddle steamer, ran aground crossing the English Channel in a snowstorm. She was sighted by a lookout at Goodwin Sands at the start of World War II. A lifeboat went out to investigate — but no ship was found.
