I recently sold my 1875. Lived most of its life on Mille Lacs…never felt unsafe, but there were days I didn’t dare go out. The 1775 should be fine for 90% I’d say. I think it’s more on the driver than the boat.
I would spend a little more and get the 1875, you get the 150hp instead of the 115hp and the gained length and depth will work fine for your big water lakes.
I run mine on Vermilion a lot, ran across big bay in 3 footers last summer. I’m sure an 1875 would be better but I was fine. Be a smart captain and you’ll be okay. It’s much better than my 1700 Pro Sport was on big water and the sport top is awesome for keeping you dry.
