This is what can happen if you leave the dock.....
Been there, done that, repaired it myself.Actually I've done this a couple of times. (Don't tell anyone, I'm still trying to perpetuate the illusion that I know where the water is deep)Get yourself some blocks of wood that will support the underside of the wing and a 2# sledge hammer. Eat your Wheaties and go at it. Don't be afraid to really lay into it, it will take quite a beating to get it back in shape.After you have it roughly in shape, fill any low spots with a thickened epoxy and sand smooth to fair the shape. You may want to drill some 1/4" holes into the area you are filling so the epoxy has some nooks to hook into.The only caution I can offer is to hammer the lead so that it resumes it's original shape in small steps. Don't try to whack it back in just a few hits or you may end up breaking off a piece. If you do break off some, just fill it with epoxy. The loss of even a few pounds of lead is not a big deal.
