I had a great time doing the "simple" races that day because there wasn't such a distance between boats
AHA! And that is exactly what will keep the beginner interested and coming back. A short course where the leaders are still in site. Maybe one can learn a bit more about the rules and boatspeed. And if the cereberal part of the game is too daunting they may give up. Bubba and Cleatus win few, if any, drag races unless they seriously study boat speed. If properly put in front of the couch potato it will draw attention. As stated earlier, with the proper commentator and explanations even "boring" F1 can be entertaining to watch...you know I might be able to afford a sailboat.
