Questions
How is corrected time calculated?
Time on time (ORC ToT, IRC TCC, SRS): corrected time = elapsed time × rating, and the lowest corrected time wins. Portsmouth Yardstick: corrected time = elapsed time × 1000 ÷ Portsmouth Number. Each formula is shown next to the results with a link to the official source.
Which ORC number do I use?
The time-on-time coefficient your sailing instructions specify — ORC certificates give ToT values for different course models. ORC defines ToT = 600 ÷ ToD. Time-on-distance and performance-curve scoring are not in this calculator.
Is LYS included?
Not as its own option: we only list systems whose formula we could check in an official source. If your notice of race says corrected time = elapsed × your rating, use “Other time-on-time factor”.
How do I score an average-lap Portsmouth race?
Choose Portsmouth Yardstick and fill in the laps each boat sailed. The calculator uses the RYA average-lap formula: elapsed × most laps × 1000 ÷ (PN × laps).
What about boats that finish after midnight?
A finish time earlier than the start counts as the next day. For longer races write “+1” or “+2” after the finish time, or tick “elapsed times” and enter elapsed times directly.
How are ties handled?
Corrected times are rounded to the nearest second (IRC does this). Boats with the same corrected time share the place and the next place is skipped (1, 1, 3); for points, RRS A7 adds the points of the tied places and shares them (1.5 each). Your sailing instructions may say otherwise.
