Keeping livewell from freezing

If you are talking a regular bass boat I would think it would have to get very cold for a decent amount of time to freeze. With the boat setting in water and all the flotation foam around the livewell serving as insulation and the lid shut I would think it would have to get a lot lower then 32 to freeze jmo.

I got a call back from the marina. They are closed but he is going to meet me Friday morning and let me rent a covered slip for the night.
Thanks guys!
