«Phocea» was built in 1976, making it 50 years old. It is one of 1,812 hulls in this registry delivered that year, a cohort whose median tonnage is 4,484 GT; within it this ship is the 1,417th largest. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.

At 75.0 m overall, «Phocea» is 9.8 m longer than the 65.2 m median for yachts on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8942797 this registry holds 48 other vessels, whose median build year is 1976 and which range from 1935 to 1998. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1976.

Its IMO number, 8942797, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 4×5 + 2×4 + 7×3 + 9×2 = 177 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
