None the less, it would generate easily transmitted data, that isn't fudged by anyone. There will always be some problems with a handicapping system, no matter how you do it. At least, if you had an app that compiled the data and averaged it(them?), it wouldn't require some dear soul to do all the work. It would also be updated at some interval(automatically if you desired).
We have about 20 boats that race from time to time. There really is only one OD fleet(J22), and only about 6 of them race each year. Of the rest, most times there is one or two of the same OD in a race.
Still, it is a lot of fun, and you don't have to drive 150 miles to and again back from a race. There may be 5 of the 20 boats that are newer than 10 years old. I have one of the newer ones, and maybe the oldest one (42 year old International Tempest).
As far as RaceQ's, if you look at the youtube videos, it helps. I run it on an iphone, no problem. Takes a bit of learning to set the race up, but it is all explained in the videos.
Take a look at the Texas Centerboard Class. The seem to have a lot of fun and do a series of races. (I really need to take my dinghy and join them!!)
