No gross tonnage is recorded for this vessel, so it cannot be ranked by size. Rank is only shown where the underlying measurement exists.

In context
How Antonia Johnson compares
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.
Antonia Johnson was built in 1971, making it 55 years old. It is one of 1,927 hulls in this registry delivered that year, a cohort whose median tonnage is 2,462 GT. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.
The registry attributes 118 vessels to Wärtsilä, with a median tonnage of 14,058 GT, delivered between 1938 and 1998. See the rest of that yard’s output.
At 174.2 m overall, Antonia Johnson is 47.4 m shorter than the 221.6 m median for container ships on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7120342 this registry holds 58 other vessels, whose median build year is 1971 and which range from 1971 to 1979. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1971.
Its IMO number, 7120342, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 1×6 + 2×5 + 0×4 + 3×3 + 4×2 = 82 — and the last digit of that total, 2, must equal the seventh digit, 2. 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.
