We got the system installed last summer. BEST idea ever!! We have a large cruiser with 14 or more ropes holding our boat and at least 1 breaking every week. We are on a main channel so very rough water. We were always worried about the boat and the thought of what would we do if all the ropes would break at once. Now we don't think about it at all. We are relaxed knowing our boat and dock work together keeping all safe and secure. Thank you to Larry and Lisa for taking away our worries with the DockGlide system.
