Interesting perspective on PHRF, which like the America's Cup nearly, if not always, goes to the fastest boat. The Cup is a a design competition within a box rule. PHRF attempts to compare unlike boats and allows wide latitude and local determination as to what is considered in the rating. The single builder J/30 raced one-design is intended to assure that the boats are the same, within the limits of class rules. It's difficult to reconcile these differences.
