No gross tonnage is recorded for this vessel, so it cannot be ranked by size. Rank is only shown where the underlying measurement exists.
In brief
The Radium Gilbert was a tugboat built for transporting supplies to, and ore from, the radium and uranium mines in Canada's Northwest Territories. Like the other tugs in the Radium Line she was steel-hulled.
She was named after Gilbert Labine, the prospector who discovered radioactive ore where Port Radium was built. She was built in Vancouver, in 1946 disassembled, so she could be shipped by rail to Waterways, Alberta. Like all vessels assembled in Waterways that operated on the Mackenzie River, and its tributaries, after she was reassembled she first proceeded downstream to Lake Athabasca, and down the Slave River, to the portage at Fort Smith. Large tractors towed even large cargo overland around large rapids there.
The Radium Gilbert spent her operational life 1946 to 1980 on Great Bear Lake.
She ran aground near Deline, the small community at the outlet for Great Bear Lake. Her wreck remained radioactive decades after she was used to ship radioactive ore.
She was dismantled, and removed, in 2003, after lying grounded, for decades. By that time the population of Deline understood the toxic legacy of the trade in radioactive ore, and the nearby wreck was a painful reminder.
In 2005 Atomic Energy of Canada published a study of the toxic legacy of the mining of radioactive ore at Port Radium.

In context
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.
Canada is the country of registry for 633 vessels in this directory. The most common class under that flag is vessels this registry holds no type classification for (404 ships), and the median vessel measures 1,800 GT. Browse every ship flagged Canada.
Narrowing to both dimensions at once, this registry holds 404 vessels this registry holds no type classification for flying the Canada flag.
Radium Gilbert was built in 1946, making it 80 years old. It is one of 79 hulls in this registry delivered that year, a cohort whose median tonnage is 2,270 GT. Across the whole of the 1940s the registry holds 1,039 vessels, median 4,053 GT. The median build year across the entire registry is 1995.
At 36.6 m overall, Radium Gilbert is 78.4 m shorter than the 115.0 m median for vessels this registry holds no type classification for on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5288891 this registry holds 12 other vessels, whose median build year is 1956 and which range from 1937 to 1965. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1946.
Its IMO number, 5288891, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 2×6 + 8×5 + 8×4 + 8×3 + 9×2 = 161 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
