I’ve done Lake MI a few times, MKE towards Grand Rapids usually, sometimes I’ll go around South. My technique is to fly high, usually with F.F.. One can average about 25-30 miles in the middle where it would be hard to reach shore. There is a ship ADS site that gives you an idea of where ships could be, I’ve found it to be fairly accurate. They may be all in the chow hall, but I envisioned ditching 1 mile in front.
I have worn a life preserver, or had it close. Yes, the water is cold even in August. One thing, flying 1800’ AGL on the Chicago lakefront doesn’t offer the best options either. The beach can be crowded, may be out in the water anyway.
One would want good weather, not the route to evaluate engine roughness.
