Greg Mortimer was built in 2019, making it 7 years old. It is one of 1,261 hulls in this registry delivered that year, a cohort whose median tonnage is 29,000 GT. 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 8 vessels to China Merchants Group, with a median tonnage of 50,508 GT, delivered between 2019 and 2025. See the rest of that yard’s output.
At 106.0 m overall, Greg Mortimer is 92.1 m shorter than the 198.1 m median for cruise ships on record, with a beam of 18.4 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9834648 this registry holds 49 other vessels, whose median build year is 2019 and which range from 2015 to 2025. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2019.
Its IMO number, 9834648, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 8×6 + 3×5 + 4×4 + 6×3 + 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.
