Crew Capacity for a 30' Sailboat?

I sent the above query out to several sailing email groups (Newport Owners Group and San Francisco Sailing, both Yahoo groups if you would like to join). Anywho, I received lots of great responses with most agreeing that more than 8 would be too many. I agreed. Then I got a response from a fellow Newport owner with a picture of his boat and 22 crew! I don't recommend it, but it can be done!
