SkunkedAgain is spot on. I have simply let the boat sit on the trailer in water over the bunks. It only takes 15 minutes or so. I'm from MN and fished open water on the Lake Minnetonka before complete ice up and the mighty Mississippi all winter in temps well below freezing and it always worked. Remember water temps a foot below the ice are 39 degrees. Water is most dense at that temp.
