Carl,
The Holder design for the Worrell was designed specifically for a downwind race. (That's what we were told at the time.) You are saying that planing-type hulls will not work if the boat is heeling. But what happens if, instead of tacking downwind as we all do these days, you sail a boat like that straight downwind, with spinnaker, and get it planing? Going fast and sailing a LOT less distance. Does that make sense? It would be nice to know what Randy's game plan was for that boat.
