Scott,
Welcome to catsailor!
Sorry if I missed your emails, I don't check the email that is linked to that site anymore (too much spam). There is still a fleet in Madison but I am no longer involved with it, as I do not live in Madison anymore. I have not updated the website but there are still fleet activities. There are about 30 cats on the beach at the surf club with racing wend and fri. nites run by fleet 136 commodore Joe Manganello. I'd reccomend going down there around 5 to 5:30 and taking a look, ask around for Joe.
Good luck! Send me a private message if you have any questions.
