This coming summer we are in a new Marina that is all side tie. I really don't like this setup so I am wondering if there is anything out there that will help keep the boat off the jetty with out using traditional bumpers. The wind is all over the place. It's either pushing the boat away or on the dock. The jetty is floating and the deck is about 18" off the water. They have 4"x 4" posts every 12' that are attached to the Jetty. I have seen these post covers below that would have the rub rail against the bumper and I have seen the spring rods.....is their anything else out there?... Or if I have no ther options what is the best thing to use to rub up against the rub rail?
