A sailboat tipped over Wednesday at 4:30 p.m. on Lake Michigan in-between Epworth and Stearns beach. The boat was a 15 foot Sunfish sailboat. These boats are manufactured to right themselves in the event of a tip, but the Coast Guard told WMOM that in this case the removable keel had fallen out. They speculate this was preventing the boat from being able to readjust automatically. The boater was a 61 year old man visiting from out-of-town. He suffered no injuries.
