How JCG Yahiko 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 1,380 gross tons, JCG Yahiko is the 62,597th 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 4.3 times smaller than the typical vessel on record here. The largest measures 499,167 GT.

Among the 611 naval / patrols held here, it ranks 126th by tonnage — larger than 53% of that group. Their median tonnage is 1,325 GT, and the largest tenth begin at 23,606 GT. The flag most often flown by this group is United States (136 ships). The yard that appears most often against it is Austal, with 33 hulls on record.

Japan is the country of registry for 2,663 vessels in this directory, of which JCG Yahiko is the 1,021st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (1,534 ships), and the median vessel measures 764 GT. Browse every ship flagged Japan.

Narrowing to both dimensions at once, this registry holds 66 naval / patrols flying the Japan flag, of which 22 are larger by tonnage.

JCG Yahiko was built in 1995, making it 31 years old. It is one of 1,092 hulls in this registry delivered that year, a cohort whose median tonnage is 7,255 GT; within it this ship is the 832nd largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.

The registry attributes 161 vessels to Sumitomo Heavy Industries, with a median tonnage of 51,956 GT, delivered between 1959 and 2022. See the rest of that yard’s output.

At 94.0 m overall, JCG Yahiko is 7.5 m longer than the 86.5 m median for naval / patrols on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9138472 this registry holds 76 other vessels, whose median build year is 1997 and which range from 1991 to 2004. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1995.

Its IMO number, 9138472, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 3×5 + 8×4 + 4×3 + 7×2 = 142 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
