SS Atlantic

At 18,100 gross tons, SS Atlantic is the 27,944th 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 3.0 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 617 passenger vessels held here, it ranks 16th by tonnage — larger than 97% of that group. Their median tonnage is 909 GT, and the largest tenth begin at 9,718 GT. The flag most often flown by this group is Egypt (65 ships). The yard that appears most often against it is Meyer Werft, with 16 hulls on record.

SS Atlantic was built in 1953, making it 73 years old. It is one of 179 hulls in this registry delivered that year, a cohort whose median tonnage is 3,502 GT; within it this ship is the 4th largest. Across the whole of the 1950s the registry holds 2,005 vessels, median 960 GT. The median build year across the entire registry is 1995.

The registry attributes 1 vessels to Sun Shipbuilding & Dry Dock Co., with a median tonnage of 18,100 GT, delivered between 1953 and 1953. See the rest of that yard’s output.

At 171.9 m overall, SS Atlantic is 110.9 m longer than the 61.0 m median for passenger vessels on record, with a beam of 23.2 m and a draft of 8.5 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5028837 this registry holds 11 other vessels, whose median build year is 1952 and which range from 1932 to 1960. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1953.

Its IMO number, 5028837, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 0×6 + 2×5 + 8×4 + 8×3 + 3×2 = 107 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
