Bob H. is correct about this in regards to WWL races. I've sailed with him against a low rated mono fleet, in windy and light conditions, and it was pretty apples to apples stuff. However, on a reach, especially two sail reaching, single number phrf ratings for a multi/mono class are a joke. Simply wave to us as we blast past you across the lake. Bob must be aware of this single number rating privilege we multihull sailors have.
