How Rotenfels 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.

Rotenfels was built in 1927, making it 99 years old. It is one of 49 hulls in this registry delivered that year, a cohort whose median tonnage is 1,440 GT. Across the whole of the 1920s the registry holds 516 vessels, median 2,350 GT. The median build year across the entire registry is 1995.

The registry attributes 57 vessels to AG Weser, with a median tonnage of 10,552 GT, delivered between 1906 and 1981. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5317458 this registry holds 8 other vessels, whose median build year is 1952 and which range from 1924 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1927.

Its IMO number, 5317458, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 3×6 + 1×5 + 7×4 + 4×3 + 5×2 = 108 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
