Joe and others that are not farmiliar with the Thunderboat Reproductions Bud T-4, the hull boat is molded in a total of 11 seperate components, the hull center section, cowl, 2 outer canoes, 2 fwd ram wings, 2 rear wings, 1 horizontal wing, 2 verticle fins. The fore & aft wings are held in place by S/S sheet metal screws, so this boat could be assembled with all sorts of negative or positive incidence on any the wings. When I go back together with mine I am going to be very careful as to how the wings are positioned on the center hull section & canoes, the goal will be not to add any weight to the hull what so ever.
Chuck, perhaps all of the incidence that you have in the forward ram wings explains the boat going airborne at around the speed range of 30 mph. Personally I don't think installing a spoiler to the top of the wing is going to fix the problem, you still have to deal with the bottom trapping and deflecting the air down and still lifting the front of the boat and going airborn, 3 1/2 - 4 degrees is an awfull lot of positive incidence to try and counteract. My suggestion would be to seperate the forward ram wings fron the hull center section and reposition them to be set at 0 degrees, I know this means the possibility of repainting in that section, but it will be better than fighting a problem that won't go away. I have had my boat since since 2000, and Dick assembled and painted it for my wife when she ordered it as a birthday gift for me. I have never really ran the boat much at all fighting the canoe decks popping off. Waiting on a new set to fix the problem.
