In brief

About SS Manhattan

Full article ↗

SS Manhattan was an oil tanker constructed at the Fore River Shipyard in Quincy, Massachusetts, that became the first commercial ship to cross the Northwest Passage in 1969. Having been built as an ordinary tanker in 1962, she was refitted for ice navigation during this voyage with an icebreaker bow in 1968–69.
Registered in the United States at the time, she was the largest US merchant vessel.
In 1965, she was taken to Portland, Oregon via the Columbia River, to be cleaned and used to transport 50,000 tons of grain. The size and draught of the ship required careful preparations for her transit on the river.
Manhattan remained in service until 1987. After an accident in East Asia she was scrapped in China.

In context

How SS Manhattan 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.

United States is the country of registry for 2,278 vessels in this directory. 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 90 research / surveys flying the United States flag.

SS Manhattan was built in 1962, making it 64 years old. It is one of 285 hulls in this registry delivered that year, a cohort whose median tonnage is 924 GT. 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 12 vessels to Fore River Shipyard, with a median tonnage of 44,543 GT, delivered between 1932 and 1985. See the rest of that yard’s output.

At 306.5 m overall, SS Manhattan is 235.5 m longer than the 71.0 m median for research / surveys on record, with a beam of 148.0 m and a draft of 15.8 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5219369 this registry holds 13 other vessels, whose median build year is 1952 and which range from 1943 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1962.

Its IMO number, 5219369, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 2×6 + 1×5 + 9×4 + 3×3 + 6×2 = 109 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
