yes and they also handicap race the entire fleet using three ratings. THAT is the fleet building move....

How many alu masted A cats do you foresee trekking to Florida? How many strait board A cats....

The key number is how many competitors do you actually race against. I don't see the wisdom or fun factor in two or three small fleets. The aussies solved the problem by racing a single large fleet on handicap for their NAs and trophied divisions as well.
