We have to do something to sell the brand;
Noob regatta, experienced sailors come out and sail with newbies on day 1 on their boat, then day 2 they sail with you on an F18 etc. You could just put all the shiny hardware aware and sail their boat all weekend. Teach them to sail.
Have a Friday "learn to sail a cat clinic" at every regatta this year, seriously, make it a point to bring the FNG's sailing expertise up, and do it at every regatta.

Have more non-racing sailing weekends, invite other classes and non-sailors, no racing!

Many new people are intimidated by the new boats, and races that everyone has finished except the new guys will make some not want to come back. I know we have all been there, but now kids can just say screw it Im going to play video games!
