The high sides does have a Little impact on trolling with the trolling motor like I do, but not that bad IMHO. The depth of the boat in the water for mine is only about 1' so it's not going to make that much difference. They are great in rough water. The ride in my Lund is incredible and can't imagine any boat taking rough water any better.
I had a pontoon and now that is like a sale in the wind. I would not trade my Lund for anything!
You can bet any boat with less width is going to be less stable when walking around.
