Portsmouth Yardstick calculator
Turn elapsed times into corrected results so a mixed fleet of different classes can race on level terms. Pick a class for its Portsmouth Number, or type your own. Nothing is saved, and no account is needed.
How it works:
corrected = elapsed × 1000 / PY
A lower corrected time is the better result.
Total time on the water. Accepts mm:ss, h:mm:ss, or seconds.
