A Coast Guard flight surgeon said the symptoms appeared to be that of a heart attack and recommended the man be taken to a hospital as soon as possible.
The tug altered course to facilitate the evacuation due to heavy storms in the area and rendezvoused with the Coast Guard helicopter crew once conditions allowed. The helicopter crew hoisted the man from the tug and departed for Sturgeon Bay Airport.
Weather conditions diverted the helicopter crew from its original destination but the crew safely arrived at Ephraim-Fish Creek Airport in Ephraim, Wisconsin, where emergency medical crews were waiting.
The Coast Guard was notified via VHF-FM marine radio. The man’s current condition is unknown.
