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 9,214 gross tons, MV Matanuska is the 37,097th 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 1.5 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,234 ferrys held here, it ranks 294th by tonnage — larger than 67% 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.
United States is the country of registry for 2,278 vessels in this directory, of which MV Matanuska is the 337th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.
Narrowing to both dimensions at once, this registry holds 33 ferrys flying the United States flag, of which 2 are larger by tonnage.
MV Matanuska was built in 1963, making it 63 years old. It is one of 270 hulls in this registry delivered that year, a cohort whose median tonnage is 1,002 GT; within it this ship is the 15th 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 12 vessels to Lockheed Shipbuilding and Construction Company, with a median tonnage of 9,214 GT, delivered between 1954 and 1977. See the rest of that yard’s output.
At 124.0 m overall, MV Matanuska is 20.0 m longer than the 104.0 m median for ferrys on record, with a beam of 74.0 m and a draft of 16.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5228827 this registry holds 8 other vessels, whose median build year is 1960 and which range from 1920 to 1963. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1963.
Its IMO number, 5228827, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 2×6 + 2×5 + 8×4 + 8×3 + 2×2 = 117 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
