Ok, not wanting to hijack the other thread since it's mostly related to windward leeward racing. What do you guys think would be a fair scoring system for the GT 300 or the Tybee 500. Traditionally the GT gets really reachy and favors the F18's spinnaker reaching ability. The Tybee, maybe not as much.
The GT has been raced Portsmouth since the beginning and the last two years has gone to classes with the Overall Trophy being awarded on Portsmouth. I think every year but one, it has gone to an F18 with the one exception being a Hobie 20 with a Tornado chute (nearly the same Portsmouth number as F18).
What are your thoughts?

Score it Portsmouth, Texel and SCHRS. Then add up all the corrected times and you have a wi(e)nner.

Wasn't Texel orignally used for the distance racing for the 'big one' (Ronde Texel, too lazy to look up the offical name)? SCHRS isn't too far off that, I believe.

I think a measurement system would have to be more accurate than portsmouth . Portsmouth is based on windward leeward, which most distance races are not and only updated with numbers given by races. Many OD and formula don't submit because they are not racing handicap. Does anyone know if the measurement systems use windward leeward as it's benchmark to compare the different measured boats?

How about screw scoring overall and just run one design?

There. That solves that. Next question?

Yep, that’s a great idea if everyone is on the same boat as you. You’re not a Hobie dealer are you? Some of us have what we have. And we like what we have. We also like to race what we have. You race one design. We'll work out our handicaps just fine without you. here in Az were lucky if we can get four boats on the water at the same time. We have a small group of diehards trying to get a cat following here. Trying to promote the sport to all comers. In areas like ours, we need a good handicap system.

That solves that. Next answer?

If you have a small group that wants to build a following then I suggest working on developing your own system to account for down wind only. I would use Portsmouth as a starting point and work into rating that all parties agree is fair.
First understand that none of the current rating systems can or will ever be "fair" as you are expecting the impossible. Second realize that no one has a real handle about what is the answer why one boat is fast in one direction and another one is not, yet change the sea state a little and the reverse can happen. As an example, look at the last America's Cup race. Do you really think they thought the cat would be that much slower than the tri? As another example, which rating system would you use if they gave your little group those two boats so you could race them now? Also, lets picture that you were given the ratings before the race took place, what would the rating have been? AND, would they have changed them now that the race has been run? Was the difference in speed, the boats or the sailors?
So back to the basic question, how to have a rating system that is fair for all the boats using systems for up wind down wind on a one direction distance race? Have all parties agree that the system is flawed, but by agreeing to work together you can develop something that your group can all agree to have fun sailing with..
I will warn you though, in the past I have tried something like this, where a group of us sat down and each got to pick what rating they felt they could be competitive at...what I learned form that, was there are really people out there that do not want fair. They want an advantage. Yes it is an ugly business when people want this little fun game to be more than it is...Curious no?
