How do you feel about Refirdgeration? Is it a must, a necessary evil, a huge battery drain, or do you not have it and don't want it?My current boat doesn't have refridgeration. I have an icebox which insures that I have to make land every few days to keep it cool. I really don't intend to add refridgeration to the boat because it is expensive and I would rather just get ice since I coastal cruise.At the dock I don't leave my electronics on for many reasons. I know that other boats that were in my marina that have refridgeration and leave them on had nasty powerbills this past year (we didn't even get a warning that they would be sending out powerbills because they have never charged for this before and it was like 8 months of usage).
