@rodltg2 wouldn't that just be a cable course? Just get rid of the bus! Pull a Dumb sled with a hull that is identical to a current model. Weight it appropriately, etc. you could put a judge or judges in the 'boat' with whatever electronics you'd need or want. That thing could then go up ad down the lake all day long powered from the shore.
Back to the original post, the electric option is pretty cool but likely not practical as discussed.
