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 2,508 gross tons, MV Polar Princess is the 54,759th 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 2.4 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 58,086 vessels this registry holds no type classification for held here, it ranks 31,075th by tonnage — larger than 37% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.
Norway is the country of registry for 3,032 vessels in this directory, of which MV Polar Princess is the 1,419th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (2,126 ships), and the median vessel measures 3,102 GT. Browse every ship flagged Norway.
Narrowing to both dimensions at once, this registry holds 2,126 vessels this registry holds no type classification for flying the Norway flag, of which 956 are larger by tonnage.
MV Polar Princess was built in 1985, making it 41 years old. It is one of 1,312 hulls in this registry delivered that year, a cohort whose median tonnage is 4,782 GT; within it this ship is the 810th 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 76 vessels to Havyard Ship Technology, with a median tonnage of 2,807 GT, delivered between 1957 and 2021. See the rest of that yard’s output.
At 76.2 m overall, MV Polar Princess is 38.8 m shorter than the 115.0 m median for vessels this registry holds no type classification for on record, with a beam of 14.0 m and a draft of 7.1 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8501074 this registry holds 45 other vessels, whose median build year is 1986 and which range from 1985 to 1988. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1985.
Its IMO number, 8501074, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 5×6 + 0×5 + 1×4 + 0×3 + 7×2 = 104 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
