Cool looking place!! If you are going to use a planer board to get your shad down 20' that will really increase the water drag and the amount of tension on the clip necessary to hold all that without tripping it. I'd think at least a three foot RC boat with a good amount of beam would be necessary to not tip over with the weight of the water drag and then the tug when fish is struck to release clip. Interesting postulation here, I hope you rig up something cool that works and can show it to all us other fishermen who want to get their bait where no bait has gone before.
