 says he “was traveling downwind … and performed a maneuver to change course … 
During the maneuver, the boat lost control and tipped over, causing the captain 
to fall overboard. … The boat then collided with a race committee boat.”

So maybe he had to gybe to avoid the RC boat, and broached in the process.  The 
Star has a big main; may be challenging to gybe safely in strong wind.

The surface water temperature at Dillon Reservoir is probably 45-50F right now, 
decreasing with depth.  That would induce cold shock immediately.  Here’s an 
article on the stages of cold water immersion:

<https://www.soundingsonline.com/voices/hypothermia>. Four years ago when I 
pulled three people out of Chatfield Reservoir whose fishing boat had sunk on a 
rough night, one of them was already in the second stage (cold incapacitation) 
after only five or ten minutes in the water.  The date was June 10th, 2016 and 
the water temp was sub-60F.

Cheers,
Randy
