You can wear you bathing suit at 30 below, they all have heaters. Jeff they only so i think 50 or so in the water. Flat bottom, little rough,and a real bitch to dock with no reverse. There made for ice and snow. When I said over 80MPH I was in it and there was lots left. It pulls diferent, when you start off you floor it , it doesn't pull that hard but as you get going it pulls harder than many performance boats. Just something else we do in the winter.
