But with both fleets capable of being scored individually, why rely on a number to determine who the best sailor was?
With two one design fleets... Which one is the best sailor? That is the potential problem.
Do you agree that the PR folks want one person who won the race that day. "aka the best sailor"?
Two OD fleets need some resolution of that question if you ask the question. "should the T500 be scored on corrected or one design. (or elapsed)
The whole discussion is irrelevant IF the F18 fleet thinks that they are equal to the N20 in speed IN THIS UNIQUE RACE, . Wouter's suggestion would make the most sense. Race elapsed 1 to 20 and then award OD trophies.
If you think the F18 is slower and you have no chance at line honors and the overall win... You might want a PN race or a volvo/regatta type scoring to level the field.
Remember, In the 18HT fiasco worrel. the PN differences based on around the cans for the 18HT and the N20 was very small. So the 18 footers thought they had a shot at line honors in the new Tybee 500. When the results proved otherwise... people played with the ratings off line to level the field.
If the race is for two one design fleets and you don't need a single winner of the day for the PR value. ... duplicate the big trophy and don't tabulate the elapsed time results or recognize the elapsed time winner with a trophy. Leave it to the public to opine about which team, which boat, which class did the best.
For years the Down the Bay, run north to south with prevailing southerly's... the elapsed time winner would go to a classic Tornado, the scratch boat in the fleet. Was this accomplishment worth a trophy? If he wasn't the first boat to the beach... he had no chance of winning the official race on DPN.
