Wow..an hour. We get some pretty cold temps up here and usually by just launching boat and letting it set in the water on the trailer will thaw it out enough to get it off in five or ten minutes. These are aluminum 16 to 18 foot Jon boats we duck hunt out of. Try putting some of the EZ slide teflon pads on your carpeted bunks, know some guys that use em and say they work. Cabelas or Bass Pro carry them.
