Yep! you're right.
Steve is right about the frac rigged spinn halyard on the stock boat. Mark, I am putting a masthead spinnaker on the boat along with a custom retractable bow sprit which I am just now completing. This setup will allow me to carry a larger akite and sail deeper than the conventional setup. I figured that JBoats(among others) do it so why not try it. The big gain is carrying a larger sail area with less crew and more speed. I expect the PHRF committee to smack me with a pretty good penalty, but we are already able to sail way above our rating.
