Gedser

At 14,540 gross tons, Gedser is the 31,271st largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 2.4 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 877 ro-ros held here, it ranks 270th by tonnage — larger than 66% of that group. Their median tonnage is 7,395 GT, and the largest tenth begin at 34,011 GT. The flag most often flown by this group is Italy (62 ships). The yard that appears most often against it is Flensburger Schiffbau-Gesellschaft, with 16 hulls on record.

Gedser was built in 1976, making it 50 years old. It is one of 1,812 hulls in this registry delivered that year, a cohort whose median tonnage is 4,484 GT; within it this ship is the 438th largest. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.

The registry attributes 56 vessels to Elsinore Shipyard and Machine Construction, with a median tonnage of 6,332 GT, delivered between 1919 and 1984. See the rest of that yard’s output.

At 144.0 m overall, Gedser is 19.1 m longer than the 125.0 m median for ro-ros on record, with a beam of 24.4 m and a draft of 6.9 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7358743 this registry holds 69 other vessels, whose median build year is 1975 and which range from 1974 to 1977. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1976.

Its IMO number, 7358743, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 3×6 + 5×5 + 8×4 + 7×3 + 4×2 = 153 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
