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 321 gross tons, Leonardo (A 5301) is the 77,493rd 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 19 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 44,466th by tonnage — larger than 10% 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9251303 this registry holds 72 other vessels, whose median build year is 2002 and which range from 2001 to 2004. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2002.
Its IMO number, 9251303, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 5×5 + 1×4 + 3×3 + 0×2 = 113 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
