Does anyone make a keel protector for a cat hull so I don't leave a little piece of my boat on every beach I pull up to? It seems if I buy 2 keel guards from a v hull the angles won't be sharp enough and eventually will pull off...any one have a cure for this problem?

look for the canoe keel guards, ("Keeleasy") you from it with a heat gun. Canoes probably a steeper bow angle than a cat.
