It's is hard to give you prop suggestions when we don't know what size and style of hull you are planning to use. Also your engine will play a large part as well. The combination of these factors will help determine what props. Now you're talking a couple hundred yards you will want a large boat to see what you're doing. Probably a deep vee or a tug boat style hull will be best, but BIG! At that point you're probably better off using a real boat and dropping the line yourself. I'm not against people experimenting and conquering an idea. But I did want to point a few things out. I wish you the best and I hope you keep us posted on any progress, I'll be watching.
