I have just realized I have cracks on both the forward and aft sides of my keel. They are each about 3 inches long. Is this common for Hunter 28.5? What needs to be done to fix the problem? Any ideas. Should I pull the boat out of the water immediately, or could this wait until the end of the sailing season before I fix it? Is this something that could be fixed by a novice?Thanks,Rick Heffner
