I just purchased a used C-sprite 18 foot Jon boat. I'm concerned about the keel as I fish a river with just a ramp (no docks) so beaching it all the time will scrape the keel. This boat has some wear on the keel already. There is no pronounced keel like on a semi V, but rather four keels. Other than purchasing expensive keel protectors, is there any other way to protect not only the keel as well as the bottom. I've read about using garden hose? If so what type of adhesive would be used to attached it. Also is there any benefit to painting the bottom with a rhino lining for added protection. Thanks, Basher 55
