From the YC point of view ... it's the same amount of effort by your volunteers and so why give up your regatta to Sailing World.
I am curious if you picked up any converts with your show of force in the NOODs last year. Every Dinghy or Cat class that I know has this fond dream that they would gain converts if only the monohull sailors would see us.
I wonder if it works?
Yes,it works. We had a couple of "converts", and they are putting peer pressure on others to get onboard.
More and more I here the phrase, "I saw you guys at the ________ event. "
We had several conversations at the begining of last year on the subject of particapating in events outside of our already full schedule.
If you're not out there making your presence known, and just assuming interested parties will seek you out; you are not doing your group justice.
The down side is that it takes longer to rig the boat with so many guys coming up and wanting to talk about the boat.

The NOOD event offers more bang than most clubs can offer on their own. I would try to find a way to incorporate the NOOD event into your current schedule. The NOOD event here was the way many classes showplaced their regional championships.
