To add any boat, paste its public ORC certificate link on that boat's profile page. ORC certificates and IRC published boat data also link automatically overnight.
The selection ordered by rating, fastest first. The gap is what the slower boat gets back in corrected time - per hour of racing under IRC, per mile under ORC.
Gaps are cumulative from the fastest-rated boat in the selection.
Every boat holding both ratings, two independent measurement rules assessing the same hull. The line is this fleet's trend; boats off it are the ones the rules disagree about. Hover for the size of the disagreement; click a dot to add the boat.
Speed predictions from each certificate's velocity prediction program. Further out is faster at that angle; diamonds mark upwind and downwind VMG. Hover any point for the numbers.

Pick a family of measurements. The bar under each value shows where it sits in the range across the selection - longer means bigger, not better.

|---|---|---|
| Length overall (m) | 10.97 | 8.95 |
| Max beam (m) | 3.41 | 3.26 |
| Draft (m) | 2.44 | 1.69 |

Hull and stability numbers in sailing trim.
Races where at least two of the selected boats finished, scored under each measurement rating system the race carried - places are in the full division, margins in corrected time, exactly as the club published them.
Checking the results…
All figures come from each boat's public ORC certificate or IRC published boat data (IRC TCCs from club records); speeds are the ORC certificate VPP's predictions, not observed results. Measurements move together with boat size, so no single number explains a rating. The fairest comparisons are between boats of similar size or within one design classes.
