The provided context contains no information about ships docked at Nantucket. Without a source text, passenger manifest, harbor log, or historical record referencing specific vessels at Nantucket's docks, it's impossible to identify which ships were—or were not—present at any given time.
Historically, Nantucket hosted whaling ships (18th-19th c.), coastal schooners, and later steamers. The Straight Wharf and Old North Wharf were primary berths. Famous ships: Essex (whaleship, sunk 1820), Charles W. Morgan (last wooden whaleship, now Mystic Seaport). But without a specific query context, any answer would be speculation.
Please provide the source material or specific scenario for a definitive answer.
