A little over a week ago I was snorkeling in 80 degree F water in Bonaire and enjoying ice in Boat Drinks. Yesterday I was on my boat looking at ice in the boat. A little in the bilge and the Brita water container frozen solid.
That will have to wait until warmer days to remove. It was also too cold to work on board I just sat by the heater and waited until the batteries get a top up charge.
