At 17,679 gross tons, Sea Brave is the 28,403rd 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 2.9 times the typical vessel on record here. The largest measures 499,167 GT.

Sea Brave was built in 2004, making it 22 years old. It is one of 1,485 hulls in this registry delivered that year, a cohort whose median tonnage is 17,188 GT; within it this ship is the 711th 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9279551 this registry holds 60 other vessels, whose median build year is 2004 and which range from 2002 to 2006. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2004.

Its IMO number, 9279551, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 7×5 + 9×4 + 5×3 + 5×2 = 171 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
