T&T: "the best" AC system?

[Robert Hagens]

I have noted reference to "chilled water" A/C. How is that different?
Better? More expensive?

Thanks,
Robert Hagens

On my Krogen 42, it takes 2 - 16,500 BTU units to keep the boat cool in the 
hot summers we have here on the Gulf coast. And that's with the PH windows 
insulated with that foam/foil laminate they use to sheath houses with. 
Before I used that, I had Textilene covers on the outside of the windows, 
and it helped, but not nearly as much as the foam. With the windows 
uncovered, it's like a damm greenhouse in the summer and the AC will never 
keep up!

I have one mounted under the watch berth in the PH port side. The return air

is on the side of the berth, and it blows into the pilothouse and back into 
the saloon through two vents, one under the watch berth facing forward and 
the other above the ladder going down into the companionway. The thermostat 
is above said ladder.

The other unit is mounted forward of the chart drawers and steering station.

It pulls air through a vent in the forward hanging locker, and blows cool 
air into the pilothouse and the forward cabin. The PH vent is in front and 
slightly left of the compass; the vent in the forward stateroom is on the 
forward side of the hanging locker.

One seawater pump is mounted in the forward stateroom bilge, and supplies 
both units. I can send pix if you'd like.

I would HIGHLY recommend the Mermaid units. I did a LOT of research before 
buying one, and they came out on top by far. Five year unconditional 
warranty, SS construction, very quiet and efficient. Mine has been running 
perfectly since around 2002. Very nice people to work with. The only problem

is that if it needs warranty work, you have to send it back to the factory. 
Of course you could get somebody local to fix it, but the point is it 
probably won't break down, at least not for a long time! The unit is 
self-contained and very easy to install yourself. Just needs 110V, raw water

supply, drain, and ducting.
