How USCGC Mackinaw 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8640210 this registry holds 15 other vessels, whose median build year is 1974 and which range from 1863 to 2002. That places this hull’s registration in the same part of the series; no build year is recorded for this vessel itself.

Its IMO number, 8640210, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 6×6 + 4×5 + 0×4 + 2×3 + 1×2 = 120 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
