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.

ACV Ashmore Guardian was built in 1983, making it 43 years old. It is one of 1,578 hulls in this registry delivered that year, a cohort whose median tonnage is 3,112 GT; within it this ship is the 1,347th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.
The registry attributes 1 vessels to K Shipyard, Fremantle, Western Australia, with a median tonnage of 339 GT, delivered between 1983 and 1983. See the rest of that yard’s output.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8215285 this registry holds 37 other vessels, whose median build year is 1983 and which range from 1982 to 1985. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1983.
Its IMO number, 8215285, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 2×6 + 1×5 + 5×4 + 2×3 + 8×2 = 115 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
