I'd say it dpeends on where you keep your boat. If the water can freeze up and lock you in, you could be in trouble. If you are in deeper, moving water that usually doesn't freeze over than I would say try to stay in as long as possible. The winter blackfishing at 17 the last few years has been outstanding. The bass fishing in late Nov and early Dec is also outstanding! If you dress warm and have protection on your boat, go enjoy the great fishing. fyi... I wear a a pair of scuba gloves and they are great. THey keep your hands warm, you can feel the line and fish, you can grab the fish easily without fear of being pricked and you can put your hands in water and not freeze! Also the helly hansen thermals keep ya toasty!!
Keep an eye on the winds and weather. Make sure your electronics are working. It can get lonely out there sometimes...
