Sumela Seaways was built in 2008, making it 18 years old. It is one of 2,764 hulls in this registry delivered that year, a cohort whose median tonnage is 8,971 GT. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.
The registry attributes 118 vessels to Flensburger Schiffbau-Gesellschaft, with a median tonnage of 24,046 GT, delivered between 1900 and 2022. See the rest of that yard’s output.
At 223.3 m overall, Sumela Seaways is 98.4 m longer than the 125.0 m median for ro-ros on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9356749 this registry holds 66 other vessels, whose median build year is 2008 and which range from 2005 to 2011. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2008.
Its IMO number, 9356749, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 5×5 + 6×4 + 7×3 + 4×2 = 159 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
