@Hucklefin If your going to use a floating course and try and make it semi permanent there is only one choice, Accufloat by Mike Suyderhound. It is the best made course and is stainless cable. If your neighbors would be ok with leaving 8 buoys on the surface you can float this course in less then 15 minutes. You put a tag line with a jug or buoy at every gate. Drive up to the buoy, pull the cable to the surface and put the ski buoys on.
