size of the air units on a 36 mariner

I have a 36 trojan off-shore or sedan/bridge, I have an 18,000 btu unit reverse air, I don't think you can get a single 120 volt that big anymore. It works well as long as I have the cover on the windscreen, the cover is off white material, they kind that you cane see thru, we also have to hang a curtain outside the glass back door in real hot weather.
If I had to replace it I think I'd get a 16,500 and a 8,000 btu, the unit I have is heat exchangers and fan all in one unit, then you run 4 or 6 inch duct to the different areas of the boat. I would duct the 16,500 the same way the 18,000 I have now is and the 8,000 only to the salon. The 18,000 I have now is ducted to the salon, vee bunk and head the dinette is the lowest part of the boat and is in between all of them. If I had the 16.5 and 8 I don't think I'd have to hang the aft outside curtain. I would only run the 8 if the back was in the sun.
Remember with ac too much is not good, humidity has to be removed, 68 degree 70% humidity air is not cool. You need it to run most of the time to remove the humidity.

Thanks.. I am trying to buy a FX-1 digital controller for my existing units ( which are still running well ) They need the btu uto supply the correct box..
Let me know how the installation works out - we have pretty much the same set up and the old rotary knob - on like a blast furnace/freezer - off - would be nice to regulate.
Don't know what the BTU's of our unit is - sorry.

I replaced all of the old analog controls with the FX digital controls on my 42 aft cbn and love the FX controls.

I hear you with the blast furnace... Mine is soooo loud in the salon.. I'm thinking about adding a split off somehow to diffuse the racket as well.
The fan on mine on low is still about 3x the volume I'd prefer - not sure if the digital can somehow correct that too? Will the whole system (including fan) cycle on and off like a/c at home? With the rotary controls the compressor will kick on and off but the fan stays constant
If you leave the a/c on at night you could about hang meat by morning even off full cool.
Good luck with the project!
