At 4,160 gross tons, GMV Aramoana is the 47,089th 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 1.4 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,234 ferrys held here, it ranks 433rd by tonnage — larger than 51% of that group. Their median tonnage is 3,908 GT, and the largest tenth begin at 25,454 GT. The flag most often flown by this group is Japan (241 ships). The yard that appears most often against it is Mitsubishi Heavy Industries, with 34 hulls on record.
GMV Aramoana was built in 1962, making it 64 years old. It is one of 285 hulls in this registry delivered that year, a cohort whose median tonnage is 924 GT; within it this ship is the 29th largest. Across the whole of the 1960s the registry holds 4,074 vessels, median 844 GT. The median build year across the entire registry is 1995.
The registry attributes 31 vessels to William Denny and Brothers, with a median tonnage of 2,283 GT, delivered between 1900 and 1962. See the rest of that yard’s output.
At 112.2 m overall, GMV Aramoana is 8.2 m longer than the 104.0 m median for ferrys on record, with a beam of 18.6 m and a draft of 4.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5021671 this registry holds 11 other vessels, whose median build year is 1956 and which range from 1922 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1962.
Its IMO number, 5021671, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 0×6 + 2×5 + 1×4 + 6×3 + 7×2 = 81 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
