In context
How USS Anoka 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.
USS Anoka was built in 1971, making it 55 years old. It is one of 1,927 hulls in this registry delivered that year, a cohort whose median tonnage is 2,462 GT. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.
The registry attributes 16 vessels to Peterson Builders, with a median tonnage of 3,162 GT, delivered between 1970 and 1986. See the rest of that yard’s output.
At 33.2 m overall, USS Anoka is within a metre of the 32.3 m median length for tugs on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8980921 this registry holds 41 other vessels, whose median build year is 1967 and which range from 1955 to 2004. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1971.
Its IMO number, 8980921, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 8×5 + 0×4 + 9×3 + 2×2 = 181 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
