Nice looking boats! I know most of you race IMPBA and I do not know the set of rules you race under, but if you plan on racing in a NAMBA event you need to make sure you look over section 20 of the rule book that you can get at www.NAMBA.com. I have seen photos posted here of boats that would not be legal at a NAMBA event. I know that many local clubs fail to enforce the rules thinking they are helping out but in fact that can hurt. If all along a guy is running a boat at his local club and decides to take their racing on the road to see how they stack up at the National level only to be told he can't race until he covers his pipe, has too deep of pickle fork, Has no numbers or sponsor name, has hydro shoes... that hurts not helps. Section 20.b.5 of the NAMBA rule book states " There will be no exposed tuned pipes allowed. Tuned pipes will be covered by a deck, a cowl, or an exhaust shroud..." . Make sure if you race NAMBA sport classes that you read section 20. If you have questions please either call or email the Sport Hydro chairman for clarification. If you know of a local racer that has a boat that is not legal don't tell him all of a sudden he can't run but give them a race or two and help them to fix the problem. This way if they decide to go race in other parts of the country or to a National event they will not get caught off guard with a boat that can't be raced.
