I've been reading through quite a few posts here on RCU and the other RC site and have noticed that these Prather tunnel hulls are quite often bashed for them being outdated. I bought one of these hulls,(32" Racing Hull) used, on Ebay a while back and am in the process of putting it together. What are the differences between these hulls and the newer tunnel hulls? I doubt that I will do any racing with this boat, but would like to at least have some fun with it. Would I be able to expect a fair amount of performance from this "outdated" hull running a K&B 7.5cc outboard with tuned pipe?
