Installed 42 of these bungys on 7 mooring lines (6 pcs per line) on my 48 foot catamaran (17 tons). It is extremely fast and simple to install them compared to other shock absorbers or stainless steel springs & chains like I used to have. All mooring lines can stay in place; you just need to slack them one by one while you install the bungys. I went for 6 pcs per line (following manufacturer's recommendation), however, after seen their stretch and built quality, I think 4 or 5 would probably been enough. Better safe than sorry, they are so cheap (compared to other systems) that I prefer to have a few more. The first real proof of quality came when a large vessel passed by my mooring. This would usually result in big surges & heavy shock loads on my cleats. Not anymore!!! The boat just gently moves back and forward, no more squeeking of ropes. I am seriously impressed. Hats off to the makers!! Oh, yes I have read several testimonials that these things are still in great shape after 20 (!) years!! Now THAT is incredible.
