How YM Witness 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 144,651 gross tons, YM Witness is the 1,585th 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 24 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,881 container ships held here, it ranks 281st by tonnage — larger than 92% of that group. Their median tonnage is 33,698 GT, and the largest tenth begin at 140,096 GT. The flag most often flown by this group is Liberia (498 ships). The yard that appears most often against it is HD Hyundai Heavy Industries, with 348 hulls on record.

Hong Kong is the country of registry for 2,385 vessels in this directory, of which YM Witness is the 209th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (1,478 ships), and the median vessel measures 33,042 GT. Browse every ship flagged Hong Kong.

Narrowing to both dimensions at once, this registry holds 186 container ships flying the Hong Kong flag, of which 40 are larger by tonnage.

YM Witness was built in 2015, making it 11 years old. It is one of 1,804 hulls in this registry delivered that year, a cohort whose median tonnage is 25,303 GT; within it this ship is the 63rd largest. Across the whole of the 2010s the registry holds 20,111 vessels, median 23,456 GT. The median build year across the entire registry is 1995.

The registry attributes 1,092 vessels to HD Hyundai Heavy Industries, with a median tonnage of 65,131 GT, delivered between 1970 and 2025. See the rest of that yard’s output.

At 368.0 m overall, YM Witness is 146.4 m longer than the 221.6 m median for container ships on record and a draft of 16.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9704609 this registry holds 48 other vessels, whose median build year is 2015 and which range from 2011 to 2022. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2015.

Its IMO number, 9704609, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 7×6 + 0×5 + 4×4 + 6×3 + 0×2 = 139 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
