What the National Weather Service wrote

Wingnuts, a 35-ft sailboat, capsized while participating in the 103rd annual Chicago-to-Mackinac Yacht Race. All eight occupants were tossed into the water. Six were able to extricate themselves from the vessel, clinging to the hull until other race participants rescued them. However, the skipper and a crew member could not free themselves from the vessel when it capsized on top of them. They were found dead the next day, still tethered to the boat. These were the first weather-related fatalities in the history of the race. On a separate boat, one crew member suffered a broken wrist during the storm. Eyewitnesses indicated that the extreme winds, estimated at 60 knots, lasted for 10 to 12 minutes.
