Same yard, same years
No ship class is recorded for this vessel, so these are not asserted to be sister ships — they are contemporaries from the same builder, shown because that is what the data supports.

Measurements
Its IMO number, 8763402, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 6×5 + 3×4 + 4×3 + 0×2 = 152 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
