Another approach- and the one executed by the previous owners of our boat- is to install more than one A/C unit. You can run one, two, etc. depending upon cooling [and heating] demands. [Our 3 A/C-heater units are independently operated and located in the 3 main zones of the boat: forward, midship/pilot house, and the aft (master) cabin.]

The two forward units share one March pump as they are the two run most of the time when needed.

The idea being if- in your case- say you need 16k BTU, would you benefit from installing 2- 8K BTU units [keeping the arithmetic simplistic for this example...] You gain redundancy [albeit half capacity], reduced electrical demand when peak capacity is not required [e.g., only run one unit], somewhat lower start-up current requirements when starting independently, etc.

This concept undoubtedly does not fit all circumstances or needs, but works very well for ours.

Just another proven approach to be aware of.

Cheers! Bill

A reason I went with a 6K in our Stateroom is that a Honda will easily start in in eco mode, meaning its lots quieter and runs longer on a tank of gas.
Plus I can pretty easily run it when we are motoring off of the alternator and inverter.
Plus of course if one breaks you at least have some cooling it’s not all or nothing. For that reason I chose to have separate water pumps.

Here you go $1060.00 scratch and dent special.

I think the OP was referring to me. We have an Allied Seawind II, the next generation, slightly bloated version of the original.

Oops, I missed that. Thanks

Hello from Biloxi. I know the hot and humid you speak of

.

I am doing a refit and installed a Wabasto 16000 btu in a 36' boat with fair insulation. I made my decision based on the great advice given on this forum, as you are receiving now.

I would add that the Wabasto has, as a64pilot pointed out, the low setting that does dial back the cycling, but it also has a dehumidify mode that will quickly lower the humidity. I expect this would be a nice feature while away from the boat. I already had a 1" supply seacock that I will share with the water maker and A/C. I put in an oversized Graco bronze strainer.

as to your question about the through hulls, I did as you have suggested and installed all new Graco bronze BV seacocks. I like bronze the 655 grade in this case it will out last me.

I also did as you suggested and made my on hull flanges out of 1/2" G10 and drilled and tapped them for 3/8 silicone bronze studs. This worked great and I set them in thickened epoxy over existing thruogh holes then using a drimel tool cleaned up the hole after the epoxy set.

And it didn't happen unless I can provide pictures, right?
