Eystein Jarl

Eystein Jarl was built in 1950, making it 76 years old. It is one of 153 hulls in this registry delivered that year, a cohort whose median tonnage is 555 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.

At 72.1 m overall, Eystein Jarl is 42.9 m shorter 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 5111177 this registry holds 15 other vessels, whose median build year is 1957 and which range from 1909 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1950.

Its IMO number, 5111177, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 1×6 + 1×5 + 1×4 + 1×3 + 7×2 = 67 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
