I would leave the Hull Specs rule 5 in place. Are we talking Scale here or Sport-Scale?
If you start off with allowing foam helmets glued onto cowlings, there will never be any going back. You'll never be able to tighten up that rule again, without all of the added baloney (and wording in the rules) about grandfathering in this and that.
Start off with foam Bobble-Head boats and everyone will be doing it.
Require a driver and a couple of racers have some minor work to do. I don't get it. Why go through the trouble of modeling an Unlimited so closely, only to take the easy way out on that one detail?
If the drive dog rule is dropped, it will only give the nitro guys an excuse, saying that the electric boats have an advantage.
How about an added rule. Like Roger mentioned earlier, separating the shovelnoses from the PF hulls. At least making that the CDs choice if enough shovels show at the race. or, at least doing it in the prelim heats and bring the best of both together in the final.
Just something in the Race Format section, along this line: At the Contest Director's discretion, shovelnose hulls and picklefork hulls may be grouped into separate heats.
It would be an incentive for racers to choose a shovelnose boat. As it is, I don't think that many are choosing that option.
