I'm all for mixed fleet sailing. I don't want anyone sitting home because they don't have a fleet to sail in.
We could learn a lot from the H-17 sailor last weekend. If you keep the pointy end up, you finish more races and have an overall better result. The more skill you have the better the result will be.
For what it's worth, I had a reacher from Calvert sails on my H-17 and it was a screamer!
