It's time to replace my refrigeration on my 42. Has anyone installed the Cool Blue? Everything I have read about it sounds good. But with one plate not sure how you cool the freezer and the cool side.

I had one of their units on my H'31. It was a good unit and was not very power hungry.
I now have a Isotherm unit which I would also recommend that you look at. I purchased a SP unit which cools the unit with sea water but does not have a pump and does not have a fan.
I really cannot tell you how any of these units work with a spill over system, but I would suggest that it is properly sized with whatever unit you get. Are you going to a holding plate or evaporator system? Isotherm supports both.

water or air cooling
Water cooling is important in hotter climes but there are those nasty corrosion problems and critters setting up shop inside. Air cooling has none of those problems but suffers greatly during 90+ F summers. Mine runs 24 hours a day just trying to keep up when the temp goes above 98 F.
Air cooling is just plain easier to install too. No pump or plumbing and thru hulls

SeaFrost
On my 40.5, I went with an air cooled SeaFrost system that has been great for the last three years. http://www.seafrost.com/

Bill:
If you check out the Isotherm unit you will find out that it is not like the other units that use a pump to pump the water through the compressor. The coolant (or whatever you wish to call it) runs through a coil that is in the main sink drain for the galley. The coolant is cooled to the temperature of the seawater and not the air temperature.

so here in florida with water in the high 8o s and nights are cool it dones not work as well as air cooling.. humm then there is the damn usless march water pumps that are a pain in the butt. the extra hose the extra enegry to run the pump....
no i think air cooling is ok after all.

Air cooling
I should say that my 40.5 has an air cooled reefer and freezer and both work fine even when it is 100 F outside. I do put up the sunshades which keeps it around 80 in the cabin but the units keep everything cold / frozen fine. they just run almost all the time and my baseline load goes from 5 to 10 amps continuous.

We installed the Technautics Cool Blue in our previous boat, a Gulfstar 36. It was easy to install and impressively efficient. I liked the holding plate system better than the refrigerator systems now used on Hunters. I did drill many holes in the wall of the icebox and injected low expanding foam into the walls, which really helped the insulation.
