Re: What are some good options for refrigeration?

We picked up a used Engel fridge/freezer from another boat and I'm pretty impressed. These seem like the answer to the hassle of ice. They come in a lot of different sizes and this one (40 liters) seems to burn around one amp an hour, average.

Re: What are some good options for refrigeration?

It is likely the cost of adding any type of refrigeration to your Catalina 27 be very expensive in comparison to your boats worth. Extra batteries and or solar power to keep everything running could be a grand easily, then add the cost of those mini fridges.

I spent two weeks sailing BC, and sailed all the way up to Desolation Sound. Until you get past Desolation Sound there are places you can stop each day to get ice and groceries. Ice done right should get you at least 3 days between needing to visit a store to resupply.

12 volt Refrigeration does NOT kill batteries!
Stop saying it, it's just not true.
If you have an engine and it charges your batteries two batteries are usually all you need. BECAUSE it is very unlikely you will not run your engine to charge your batteries everyday or every other day.

12 volt Refrigeration does kill budgets because it is expensive $600-1000 for a 5-7 cubic foot box, ain't cheap!

Prices from Amazon range from ~$450 for the CF11 to ~$1100 for the CF110

I couldn't install an icebox conversion unit for less than $2K.

Re: What are some good options for refrigeration?

I looked at all kinds of options about 4 years ago. Many will poke fun but I found Walmart to be my friend. With an inboard diesel all it took was a cheap 3 cubic feet fridge bought off season for like $87, a $100 inverter which you already have and I already had a house battery. I rarely go anywhere even for a week that doesn't require some daily motoring. An hour a day keeps my one house batt fully charged. So no solar yet. I just could not bring myself to spend $k on like a Norcold and have it fail after a year. This fridge I have is very cold. Freezer works great. I can go for as long as I want with some engine recharging. I could expand things with cheap solar or a second house batt if needed. Plus if the Walmart fridge dies it goes in the dumpster without any hesitation to be replaced by an exact duplicate. Not for everyone but it works for me...

That works for many people, but norcold and others, don't fail in a year. (Don't know where that perception came from) many of them run for many years. matter of fact, many that were installed during the 80s when 12 volt Refrigeration became viable, are still running!

There are land based examples of ammonia based refrigerators from the 1940's and 1950's that still work fine. The thing that kills many of them is simple not following the instructions about having them level when stationary. Its OK for them to be at an angle when in motion however when standing still if your listing then the chromate powder will build up and clog things or condensed refrigerant will build up where it does not belong. Many times the fix is to take them out and flip them on their side for a while, upside down, on other side and then back right side up repeating the process a few times.

My thermal chip coolers that I bought over 30 years ago still run fine. The one with the aluminum liner is holding up better than the plastic lined one which now has deep spider cracks in the liner however the cooling chip still works fine. The fans have required attention to clean and lube them however they are still original too and the smaller of the two with the aluminum liner served as my construction site cooler for a number of years.

Re: What are some good options for refrigeration?

We never got into ammonia systems but I had been around it once or twice in my career. NASTY stuff!
Some interesting reading here.

You haven't had much to say.
Your original post stated that your 27' boat had no refrigeration. Do you mean there is no ice box?

No, he means no refrigeration, or air conditioning. I am going to guess this modest boat does not even have a jacuzzi.
