I'm gonna attempt to make my own sponsons. I have some scraps of the "Starboard" material that most of them are made of, but need one to use as a pattern. I will pay shipping both ways if you will let me hang on to it for a few days. Perhaps the fall or winter would be better for this. A broken one no one is using would be ideal. I really only need one side, as the opposite side will just be a mirror image.
