I installed a Keelgard on my boat about 4 yrs. ago. While it was not a "snap," it can be done by most people, but you have to follow the directions to the tee, if you want it to last. I don't "drive" up on to concrete ramps or rocks but I have beached carefully on them several times, as I often fish alone, and there is not a dock near by. I have had no proplem with it, and only wish I had done it sooner, as I did do some minor damnage to my keel, before I put it on. Oh and that's another thing, don't install it over damage that is into the glass, a little scape is OK, but if you have penetrated the smooth coat be sure to repair that first. Remember, it doesn't have to be a pretty patch, your going to cover it up. But don't cover a raw spot, or your asking for trouble. Moisture will permeate the opening and cause rot. You can bet my next boat will get a Keegard, when I by it new. Good Fishing Mate.
