MS Iona

At 184,000 gross tons, MS Iona is the 273rd 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 31 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 665 cruise ships held here, it ranks 16th by tonnage — larger than 97% 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.

MS Iona was built in 2020, making it 6 years old. It is one of 984 hulls in this registry delivered that year, a cohort whose median tonnage is 32,720 GT; within it this ship is the 20th largest. Across the whole of the 2020s the registry holds 1,769 vessels, median 29,777 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 344.5 m overall, MS Iona is 146.4 m longer than the 198.1 m median for cruise ships on record, with a beam of 54.0 m and a draft of 8.8 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9826548 this registry holds 33 other vessels, whose median build year is 2018 and which range from 2017 to 2020. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2020.

Its IMO number, 9826548, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 8×6 + 2×5 + 6×4 + 5×3 + 4×2 = 168 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
