Tweaking the Innovation

The product I was thinking about making was something that made docking a boat way easier and less strenuous. I was thinking of some sort of magnetic rope that knew how to find its way to the dock and then the fenders would automatically pop out on the side its dock next to. All you would have to do is press a button to detect the spot and it will automatically do all the work.  I would make a few different variations by some being the cheaper version, which would not automatically take out the fenders just dock the boat. The benefit of my product would be that if you are coming home from a long day out on the boat you will have one less thing to do that puts stress on you. The tangible is a magnetic rope and the automatic fenders that pop out when you click the automatic docking button. The augmented benefit would be the automatic parking and the automatic popping out of fenders. Where my innovation can be tweaked is on making an invention that is less costly.
