If we want open designs to really take off I think this is one of the routes that need to be utilized. The more we support these 6 man races the more people will have them, then they will get more exposure and eventually that will result in to more money to the sport. If you own a 6 man or can get your hands on an open design (or traditional boat) then bring out your boat and show that their is demand for these races.
Now that more races are allowing open designs; I for one will have better options and a better argument to get sponsorship money from businesses. This will help us all.
