Cerinthus

Cerinthus was built in 1954, making it 72 years old. It is one of 182 hulls in this registry delivered that year, a cohort whose median tonnage is 2,174 GT. Across the whole of the 1950s the registry holds 2,005 vessels, median 960 GT. The median build year across the entire registry is 1995.

The registry attributes 124 vessels to Harland and Wolff, with a median tonnage of 12,002 GT, delivered between 1904 and 2003. See the rest of that yard’s output.

At 169.4 m overall, Cerinthus is 54.4 m longer than the 115.0 m median for vessels this registry holds no type classification for on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5067493 this registry holds 12 other vessels, whose median build year is 1948 and which range from 1901 to 1961. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1954.

Its IMO number, 5067493, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 0×6 + 6×5 + 7×4 + 4×3 + 9×2 = 123 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
