Officials are searching Thursday for Mark Wautelet, who is in his 60s. Officials say Kewaunee Dispatch notified the Coast Guard late Wednesday of a 35-foot pleasure craft with one occupant that left the Kewaunee Marina at about 5 p.m. and was due back by about 9:30 p.m. The Coast Guard says a helicopter found the vessel beached on shore early Thursday before it left to refuel.
