Snow Drift

At 11,405 gross tons, Snow Drift is the 34,205th 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 1.9 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 494 reefers held here, it ranks 57th by tonnage — larger than 87% of that group. Their median tonnage is 5,893 GT, and the largest tenth begin at 12,345 GT. The flag most often flown by this group is Panama (80 ships). The yard that appears most often against it is Kitanihon Shipbuilding, with 24 hulls on record.

Snow Drift was built in 1973, making it 53 years old. It is one of 2,097 hulls in this registry delivered that year, a cohort whose median tonnage is 1,435 GT; within it this ship is the 459th 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 5 vessels to Chantier naval de La Ciotat, with a median tonnage of 12,958 GT, delivered between 1956 and 1973. See the rest of that yard’s output.

At 173.3 m overall, Snow Drift is 44.9 m longer than the 128.4 m median for reefers on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7228302 this registry holds 58 other vessels, whose median build year is 1972 and which range from 1972 to 1979. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1973.

Its IMO number, 7228302, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 2×6 + 2×5 + 8×4 + 3×3 + 0×2 = 112 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
