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 158,350 gross tons, Quantum of the Seas is the 974th 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 26 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 665 cruise ships held here, it ranks 27th by tonnage — larger than 95% 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.
The Bahamas is the country of registry for 1,614 vessels in this directory, of which Quantum of the Seas is the 51st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (940 ships), and the median vessel measures 30,020 GT. Browse every ship flagged The Bahamas.
Narrowing to both dimensions at once, this registry holds 133 cruise ships flying the The Bahamas flag, of which 16 are larger by tonnage.
Quantum of the Seas was built in 2014, making it 12 years old. It is one of 1,868 hulls in this registry delivered that year, a cohort whose median tonnage is 21,828 GT; within it this ship is the 44th largest. Across the whole of the 2010s the registry holds 20,111 vessels, median 23,456 GT. The median build year across the entire registry is 1995.
The registry attributes 160 vessels to Meyer Werft, with a median tonnage of 16,324 GT, delivered between 1902 and 2025. See the rest of that yard’s output.
At 348.0 m overall, Quantum of the Seas is 149.9 m longer than the 198.1 m median for cruise ships on record, with a beam of 41.4 m and a draft of 8.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9549463 this registry holds 37 other vessels, whose median build year is 2010 and which range from 2008 to 2014. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2014.
Its IMO number, 9549463, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 5×6 + 4×5 + 9×4 + 4×3 + 6×2 = 173 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
