How Tsugaru Maru compares

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.

Tsugaru Maru was built in 1964, making it 62 years old. It is one of 309 hulls in this registry delivered that year, a cohort whose median tonnage is 909 GT. 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 15 vessels to Uraga Dock Company, with a median tonnage of 5,890 GT, delivered between 1951 and 2000. See the rest of that yard’s output.

At 133.0 m overall, Tsugaru Maru is 29.0 m longer than the 104.0 m median for ferrys on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 6413895 this registry holds 14 other vessels, whose median build year is 1964 and which range from 1943 to 1964. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1964.

Its IMO number, 6413895, carries its own check digit. The first six digits are weighted seven down to two and summed — 6×7 + 4×6 + 1×5 + 3×4 + 8×3 + 9×2 = 125 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
