Alnati

At 10,444 gross tons, Alnati is the 35,168th 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 1.7 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 6,242 general cargos held here, it ranks 598th by tonnage — larger than 89% of that group. Their median tonnage is 2,963 GT, and the largest tenth begin at 10,970 GT. The flag most often flown by this group is Panama (565 ships). The yard that appears most often against it is Cestné a Stavebné Mechanizmy Tisovec, with 137 hulls on record.

Alnati was built in 1977, making it 49 years old. It is one of 1,791 hulls in this registry delivered that year, a cohort whose median tonnage is 5,622 GT; within it this ship is the 601st 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 76 vessels to Van der Giessen de Noord, with a median tonnage of 11,335 GT, delivered between 1944 and 2003. See the rest of that yard’s output.

At 143.0 m overall, Alnati is 42.0 m longer than the 101.0 m median for general cargos on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7615579 this registry holds 40 other vessels, whose median build year is 1977 and which range from 1976 to 1985. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1977.

Its IMO number, 7615579, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 6×6 + 1×5 + 5×4 + 5×3 + 7×2 = 139 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
