MS Sovereign

At 73,529 gross tons, MS Sovereign is the 6,369th 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 12 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 665 cruise ships held here, it ranks 181st by tonnage — larger than 64% 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 Sovereign was built in 1987, making it 39 years old. It is one of 819 hulls in this registry delivered that year, a cohort whose median tonnage is 1,937 GT; within it this ship is the 14th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.

The registry attributes 123 vessels to Chantiers de l'Atlantique, with a median tonnage of 63,786 GT, delivered between 1912 and 2026. See the rest of that yard’s output.

At 268.3 m overall, MS Sovereign is 70.2 m longer than the 198.1 m median for cruise ships on record, with a beam of 32.2 m and a draft of 7.8 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8512281 this registry holds 23 other vessels, whose median build year is 1986 and which range from 1985 to 1989. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1987.

Its IMO number, 8512281, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 5×6 + 1×5 + 2×4 + 2×3 + 8×2 = 121 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
