To clarify the Dog's point further, if needed, the CCA boat is, in fact, NOT sailing above hull speed. "Hull speed" may be different at different angles of heel, but it is still a derived function of LWL. To state that the boats can sail faster than hull speed, without surfing, distorts the actual architectural principle behind "hull speed".
"Hull speed" is a term used to describe the capabilities of displacement hulls. Those vessels that are able to, on occasion, surf are best considered as semi-displacement hulls at that point.
The CCA boats might then be classified as having a certain hull speed at their best point of reaching.
