the hull has to come out of a homoligated designated mold,,,and the deck as well,,, you can build the canopy,,,, u just can,t cut down the hull (free board,,lenght,,,transom,,,ect,,, or the perimetor ,,,length,,,sides,,,ect of the deck,, they have to be bonded together as factory built,,,, and added ,,canopy,,, simple,,,,,,, were trying to NOT ruin the class like the big money did super v,, a oneoff boat can be built,,, and render the other 20 boats useless, if someone is willing to build a oneoff single engine v-bottom,,and spend that much money,,, i,m sure for a little more money, an org, will make them a class, but right now the way it is , a hard working person,with the desire to race in a very competive class, can afford to. do it . with 10 /12 running now and about 8 that could brought up to specks ,,,that would be an awsome line up to be in the middle of.,, i hope this helps,,,good luck and come race
