Al Rahma

At 7,765 gross tons, Al Rahma is the 39,026th 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 1.3 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 2,411 fishing vessels held here, it ranks 30th by tonnage — larger than 99% of that group. Their median tonnage is 738 GT, and the largest tenth begin at 2,773 GT. The flag most often flown by this group is Russia (797 ships). The yard that appears most often against it is Kuznia na Rybalskomu, with 175 hulls on record.

Al Rahma was built in 1988, making it 38 years old. It is one of 920 hulls in this registry delivered that year, a cohort whose median tonnage is 1,512 GT; within it this ship is the 197th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.

The registry attributes 216 vessels to Volkswerft, with a median tonnage of 3,869 GT, delivered between 1955 and 2016. See the rest of that yard’s output.

At 120.0 m overall, Al Rahma is 66.0 m longer than the 54.0 m median for fishing vessels on record and a draft of 6.4 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8607141 this registry holds 22 other vessels, whose median build year is 1988 and which range from 1986 to 1993. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1988.

Its IMO number, 8607141, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 6×6 + 0×5 + 7×4 + 1×3 + 4×2 = 131 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
