How RV Rachel Carson 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 430 gross tons, RV Rachel Carson is the 75,410th 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 14 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 425th by tonnage — larger than 12% 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.
United States is the country of registry for 2,278 vessels in this directory, of which RV Rachel Carson is the 1,238th largest by tonnage. 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, of which 58 are larger by tonnage.
RV Rachel Carson was built in 2003, making it 23 years old. It is one of 1,383 hulls in this registry delivered that year, a cohort whose median tonnage is 11,954 GT; within it this ship is the 1,232nd largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.
At 42.0 m overall, RV Rachel Carson is 29.0 m shorter than the 71.0 m median for research / surveys on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8983210 this registry holds 18 other vessels, whose median build year is 1998 and which range from 1936 to 2003. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2003.
Its IMO number, 8983210, carries its own check digit. The first six digits are weighted seven down to two and summed — = 170 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
