In brief
SV Denis Sullivan is a three-masted wooden gaff rigged schooner originally from Milwaukee, Wisconsin. The only existing replica of a 19th-century Great Lakes schooner, she was envisioned and built by a Milwaukee-based team of professionals and volunteers and was owned by the museum Discovery World. She was the flagship of both the state of Wisconsin and of the United Nations Environment Programme until Discovery World controversially sold her to the World Ocean School in late 2022. She then moved to Boston, Massachusetts, where World Ocean School is located, although her home port is still listed as Milwaukee for ceremonial reasons and because World Ocean School plans on maintaining her connection with the city.

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 99 gross tons, Denis Sullivan is the 83,734th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 61 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 58,086 vessels this registry holds no type classification for held here, it ranks 49,487th by tonnage — larger than 0% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.
United States is the country of registry for 2,278 vessels in this directory, of which Denis Sullivan is the 1,527th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.
Narrowing to both dimensions at once, this registry holds 977 vessels this registry holds no type classification for flying the United States flag, of which 548 are larger by tonnage.
Denis Sullivan was built in 2000, making it 26 years old. It is one of 1,296 hulls in this registry delivered that year, a cohort whose median tonnage is 8,737 GT; within it this ship is the 1,230th largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.
At 26.1 m overall, Denis Sullivan is 88.8 m shorter than the 115.0 m median for vessels this registry holds no type classification for on record, with a beam of 24.0 m and a draft of 8.8 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 1100209 this registry holds 3 other vessels, whose median build year is 1952 and which range from 1905 to 2000. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2000.
Its IMO number, 1100209, carries its own check digit. The first six digits are weighted seven down to two and summed — 1×7 + 1×6 + 0×5 + 0×4 + 2×3 + 0×2 = 19 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
