Hi Mike,
It would be good to see you at the nationals. You would get to see all the boats currently being raced, and meet the class members. We pride ourselves on being very friendly, so bring your kit we may even manage to get you a sail ( depending on racing ).
I'm sure a few others will be along shortly to encourage your ideas.
You will find a Cherub very different from a 420 but I guarantee you will enjoy it.
Where do you sail currently?
