In brief
Sea Witch was a MARAD Type C5-S-73b container ship built at the Bath Iron Works shipyard for American Export-Isbrandtsen Lines. She operated in the Atlantic trades for five years. So engaged on the evening of June 1, 1973, the vessel was involved in a disastrous collision with the oil tanker Esso Brussels in lower New York Harbor and was damaged so badly that she was removed from active service.

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 21,760 gross tons, سی ویچ is the 25,512th 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 3.6 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 3,881 container ships held here, it ranks 2,298th by tonnage — larger than 38% of that group. Their median tonnage is 33,698 GT, and the largest tenth begin at 140,096 GT. The flag most often flown by this group is Liberia (498 ships). The yard that appears most often against it is HD Hyundai Heavy Industries, with 348 hulls on record.
United States is the country of registry for 2,278 vessels in this directory, of which سی ویچ is the 240th 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 49 container ships flying the United States flag, of which 35 are larger by tonnage.
سی ویچ was built in 1968, making it 58 years old. It is one of 536 hulls in this registry delivered that year, a cohort whose median tonnage is 769 GT; within it this ship is the 10th largest. Across the whole of the 1960s the registry holds 4,074 vessels, median 844 GT. The median build year across the entire registry is 1995.
The registry attributes 12 vessels to Bath Iron Works, with a median tonnage of 21,282 GT, delivered between 1931 and 1983. See the rest of that yard’s output.
At 202.0 m overall, سی ویچ is 19.6 m shorter than the 221.6 m median for container ships on record, with a beam of 76.0 m and a draft of 35.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 6806444 this registry holds 10 other vessels, whose median build year is 1968 and which range from 1967 to 1968. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1968.
Its IMO number, 6806444, carries its own check digit. The first six digits are weighted seven down to two and summed — 6×7 + 8×6 + 0×5 + 6×4 + 4×3 + 4×2 = 134 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.

No ship class is recorded for this vessel, so these are not asserted to be sister ships — they are contemporaries from the same builder, shown because that is what the data supports.
