Two people are being treated at South Haven Hospital after the boat they were on caught fire in Lake Michigan off the coast of South Haven. It happened just before 4 p.m. Monday near north beach, and South Haven Area Emergency Services says the two were rescued by another boater who was nearby. They were taken to the hospital by ambulance. A SHAES fireboat put out the flames, and the U.S. Coast Guard responded from St. Joseph as well. No cause for the fire has been determined.
