So this was interesting to look at, and in a quiet enough area could help to a degree... But Honestly I don't see a value add here unless you are horrible at docking. More then anything this appears to be a guide... Which in a rough water location could likely do more harm then good, as it simply gives the toons something to bang themselves against....

With that said, if it could get the boat out of the water, you might have a more useful product.... Pair it with something like a hydro hoist
