The USS Grampus vanished on her way home to Charleston. She was last seen by the Madison off St. Augustine, Florida, on March 3, 1843. (Winer, Devil's Triangle, pp. 67.)
"Subsequent mysterious disappearances include another U.S. schooner/warship: Grampas [sic] in March of 1843 after sailing south of the Carolinas."
Now, ladies and gentlemen, in my line of business we call this a howler. Thankfully, my grandpas have never been wrecked… I mean, my family has done a lot of crazy things, I can tell you that… They've often been wasted… But they've never been wrecked… At least not to my knowledge.
Schooner USS Grampus presumably foundered in a gale off Charleston, South Carolina with all hands. At least 25 drowned. Last heard from on 15 Mar. 1843.
How would The Donald put it? Location, location, location:
Grampus was last spoken to by Madison off St. Augustine, Florida on 15 March 1843. She is presumed to have foundered in a gale off Charleston, South Carolina with all hands. Because of that location, some credit her otherwise unremarkable loss to the Bermuda Triangle.
