In brief
About CCGS Edward Cornwallis
CCGS Kopit Hopson 1752, formerly CCGS Edward Cornwallis, is a Martha L. Black-class icebreaker of the Canadian Coast Guard. She serves as a light icebreaker and buoy tender on the East Coast of Canada. Entering service in 1986, the vessel is homeported at Dartmouth, Nova Scotia. The vessel was originally named after Lieutenant General Edward Cornwallis, a British Army officer and founding governor of Halifax, Nova Scotia. Due to the controversial history of the vessel's initial namesake, the ship was renamed in consultation with indigenous peoples, to commemorate Jean-Baptiste Cope under his Mi'kmaq name, British Governor Peregrine Hopson, and the year of the peace and friendship treaty created by former Governor Edward Cornwallis.

In context
How CCGS Edward Cornwallis 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 3,727 gross tons, CCGS Edward Cornwallis is the 48,932nd 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 1.6 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 163rd by tonnage — larger than 66% of that group. Their median tonnage is 2,180 GT, and the largest tenth begin at 9,452 GT. The flag most often flown by this group is United States (90 ships). The yard that appears most often against it is Wärtsilä, with 36 hulls on record.
Canada is the country of registry for 633 vessels in this directory, of which CCGS Edward Cornwallis is the 191st largest by tonnage. 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 38 research / surveys flying the Canada flag, of which 11 are larger by tonnage.
CCGS Edward Cornwallis was built in 1986, making it 40 years old. It is one of 866 hulls in this registry delivered that year, a cohort whose median tonnage is 4,769 GT; within it this ship is the 449th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.
The registry attributes 17 vessels to Marine Industries Limited, with a median tonnage of 3,727 GT, delivered between 1937 and 1987. See the rest of that yard’s output.
At 83.0 m overall, CCGS Edward Cornwallis is 12.0 m longer than the 71.0 m median for research / surveys on record, with a beam of 16.2 m and a draft of 5.8 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8320470 this registry holds 52 other vessels, whose median build year is 1985 and which range from 1983 to 1988. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1986.
Its IMO number, 8320470, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 3×6 + 2×5 + 0×4 + 4×3 + 7×2 = 110 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
