Is there a database of the oddballs that race that could be used to determine one off Portsmouth numbers? Such as an Inter20 without a spin, or a TheMightyHobie18 with a spin of say 350ft or a h20 with a 270ft spin or any combination of commonly raced boats with commonly available modifications. I raced once against a N5.8 with a 350 spin single-handed and a 10ft beam that still had a number around 63. (I know US Sailing has the common numbers.) What do they do with the rest? I am not whining only looking for some sort of base to work with. If this could be done nationally then some of the length classes might be able to rate boats better and start racing them against each other (20 ft boats, 18ft boats, 16ft boats.) I am not looking for opinions only if someone knows if the raw data is available to make real modifications to the portsmouth numbers.
