In context

How SS Chesapeake compares

Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.

At 27,190 gross tons, SS Chesapeake is the 21,603rd 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 4.5 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 58,086 vessels this registry holds no type classification for held here, it ranks 12,157th by tonnage — larger than 76% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.

United States is the country of registry for 2,278 vessels in this directory, of which SS Chesapeake is the 206th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.

Narrowing to both dimensions at once, this registry holds 977 vessels this registry holds no type classification for flying the United States flag, of which 84 are larger by tonnage.

SS Chesapeake was built in 1964, making it 62 years old. It is one of 309 hulls in this registry delivered that year, a cohort whose median tonnage is 909 GT; within it this ship is the 3rd largest. Across the whole of the 1960s the registry holds 4,074 vessels, median 844 GT. The median build year across the entire registry is 1995.

The registry attributes 20 vessels to Bethlehem Steel, with a median tonnage of 16,898 GT, delivered between 1927 and 1990. See the rest of that yard’s output.

At 189.0 m overall, SS Chesapeake is 74.0 m longer than the 115.0 m median for vessels this registry holds no type classification for on record, with a beam of 102.0 m and a draft of 39.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 6420056 this registry holds 9 other vessels, whose median build year is 1964 and which range from 1964 to 1965. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1964.

Its IMO number, 6420056, carries its own check digit. The first six digits are weighted seven down to two and summed — 6×7 + 4×6 + 2×5 + 0×4 + 0×3 + 5×2 = 86 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
