Wappen von Norderney was built in 1967, making it 59 years old. It is one of 496 hulls in this registry delivered that year, a cohort whose median tonnage is 757 GT; within it this ship is the 258th 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 69 vessels to Cassens Werft GmbH, with a median tonnage of 3,054 GT, delivered between 1903 and 2015. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7935395 this registry holds 12 other vessels, whose median build year is 1979 and which range from 1964 to 1979. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1967.

Its IMO number, 7935395, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 9×6 + 3×5 + 5×4 + 3×3 + 9×2 = 165 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
