You are right... there are small differences on the water between the rating systems currently. I don't expect any regattas to change in their outcome if we switch.
All this talk about SCHRS not working for the A-Class made me nervous so, just for grins I did a quick comparison. I checked to see if there was a direct relationship between SCHRS and Ports. That means can you multiply SCHRS by a constant a constant and get a Ports number. The answer was not really. If I ignore the F16 I can get a fair conversion with Ports = SCHRS * M + constant. So the 2 systems are biased differently.
Next I said, I have a bunch of boats that all have a corrected time of 60 mins. To me this means if I had identical perfect skippers all sailing the boats to their rating, how many minutes behind the fastest boat would their raw time be:
Delta Port Delta SCHRS
Tornado (classic) 0 0
F18 1.08 4.2
F16 1.44 4.38
Acat (Flyer) 2.34 2.64
TheMightyHobie18 6.48 7.5
H16 9.24 12.6
Wave 18.9 32.7
There are some small changes for the fast boats. The F16 and F18 will enjoy a small advantage over the A-Class, but the changes get bigger when you get to the slower boats.
This is not a Scientific Comparison, I am not going to argue about it but if looks to me like if you go to SCHRS slow heavy boats are gonna rule. I'm bringing a WAVE.
