It's all about conditions, on any lake but more so on the Great Lakes. Conditions can change at the drop of a hat. Never before have we had so much weather and water conditions at our finger tips as we have now with the electronics today. A smart phone can save your life. A 45 foot sailboat went down a few weeks ago near us, luck and pure luck no one was killed. Moored in a small bay on Erie and a storm kicked up in the middle of the night. The waves crashing on our new breakwall woke me. It was like glass a few hours before when I went to bed. I had to tell our new neighbours this year to make sure their camp fires are well dowsed and stuff they don't want blown away battened down before retiring for the night. One AM they woke to find their plastic patio table and chairs floating 150' out in the lake. They believe me now.
Be careful and smart and you will be fine. Smart as in that old boat is sea worthy.
1000 ton Ore Freighters have gone down here. The bottom of these lakes are littered with big ships let alone pleasure craft.
