Polyaigos

At 40,038 gross tons, Polyaigos is the 13,771st 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 6.7 times 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 7,708th by tonnage — larger than 84% 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.

Polyaigos was built in 2005, making it 21 years old. It is one of 1,690 hulls in this registry delivered that year, a cohort whose median tonnage is 12,046 GT; within it this ship is the 387th largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

The registry attributes 120 vessels to Mangalia Shipyard, with a median tonnage of 44,133 GT, delivered between 1980 and 2017. See the rest of that yard’s output.

At 228.0 m overall, Polyaigos is 113.0 m longer than the 115.0 m median for vessels this registry holds no type classification for on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9306574 this registry holds 67 other vessels, whose median build year is 2006 and which range from 2003 to 2009. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2005.

Its IMO number, 9306574, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 0×5 + 6×4 + 5×3 + 7×2 = 134 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
