What Bob said is right - and backed up by statistics.

There are 418 members of catsailor.com who have more than 10 posts. There are more people on the Hobie 16 scoresheet in North American than that (547 to be precise). I'd wager the total population of small catamaran racers in North America to somthing on the order of 4-5 thousand.

There are only 53(!) members of catsailor.com that have more than 200 posts. The active members of catsailor.com are not representative of a cross section of the population of catamaran racers in North America.

There have been, at most, 33 responses to any of these questions. This isn't a statistically significant sample to make an inference about a population.

Personally, I noticed that these forums were completely dead on the weekend of the Spring Fever Regatta. The vast majority of the "regulars" on this forum (yourself and a few others excluded), are from the south-east United States - and were at Spring Fever.
