What happened to 'Dei Gratia' crew on 'Mary Celeste'?

Exposure to rough waters and weather is a description of the happenings to the landing and sailing crew from Captain David Morehouse's Dei Gratia on the ghost ship Mary Celeste. The landing and sailing crew managed to sail the half brig in question from a position off Portugal at 38 degrees 20' North, 17 degrees 15' West Wednesday, December 4 (civilian reckoning of 24 hours from midnight to midnight) or Thursday, December 5 (nautical reckoning of 24 hours from midnight to midnight), 1872 to the Mediterranean Sea port of Gibraltar Friday, December 13 or Saturday, December 14, 1872. It was imperative to survive the extreme storms and severe waves since the part barkentine part schooner had no lifeboat other than the Dei Gratia's landing and sailing party boat.
