CC 4119 Hemerica

CC 4119 Hemerica was built in 1957, making it 69 years old. It is one of 261 hulls in this registry delivered that year, a cohort whose median tonnage is 1,300 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5268566 this registry holds 8 other vessels, whose median build year is 1958 and which range from 1945 to 1963. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1957.

Its IMO number, 5268566, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 2×6 + 6×5 + 8×4 + 5×3 + 6×2 = 136 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
