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 24,215 gross tons, SS Chusan is the 23,477th 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 4.0 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 665 cruise ships held here, it ranks 317th by tonnage — larger than 37% of that group. Their median tonnage is 43,009 GT, and the largest tenth begin at 143,289 GT. The flag most often flown by this group is The Bahamas (133 ships). The yard that appears most often against it is Fincantieri, with 112 hulls on record.
United Kingdom is the country of registry for 2,394 vessels in this directory, of which SS Chusan is the 278th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (1,835 ships), and the median vessel measures 2,515 GT. Browse every ship flagged United Kingdom.
Narrowing to both dimensions at once, this registry holds 37 cruise ships flying the United Kingdom flag, of which 13 are larger by tonnage.
SS Chusan was built in 1950, making it 76 years old. It is one of 153 hulls in this registry delivered that year, a cohort whose median tonnage is 555 GT; within it this ship is the 1st largest. Across the whole of the 1950s the registry holds 2,005 vessels, median 960 GT. The median build year across the entire registry is 1995.
The registry attributes 21 vessels to Vickers-Armstrongs, with a median tonnage of 12,653 GT, delivered between 1931 and 2010. See the rest of that yard’s output.
At 205.0 m overall, SS Chusan is 6.9 m longer than the 198.1 m median for cruise ships on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5072539 this registry holds 13 other vessels, whose median build year is 1950 and which range from 1877 to 1962. That places this hull’s registration in the same part of the series.
Same yard, same years
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.

Measurements
Its IMO number, 5072539, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 0×6 + 7×5 + 2×4 + 5×3 + 3×2 = 99 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
