Or is the water even that far down still to warm to work?

I use what is called CTD quite often, it measures temperature at depth and produces a vertical temperature profile The temperature in the water column can vary quite radically or not vary at all. The only thing you can say with any sort of consistency is that it is inconsistent.

Ya, but 5,000 BTUs is NOTHING! and that's not enough "cold" storage.

I don't think that anyone has addressed the fundamental issue for Beau:

Where are you going, what's your likely heat gain and how much heat and humidity are you trying to remove from the air?

In my opinion, 5,000 BTUs is nothing! We have two 16,000 BTU units (32,000 total) on our sailboat with no great big windows, covers over all the hatches, curtains on the ports, an insulated deck (balsa core) with a 3/4 inch air gap between the deck and headliner... And it's adequate here in Mexico. If we put up our Shade Tree awning, it's even better!

A number of folks around here have 5,000 BTU 12VDC systems. Nobody I've spoken to is happy with them. Too little capacity.

I think you need to investigate a larger system.... Or maybe a windscoop

Just to let you all know, I ended up buying a Panasonic 9,000btu "inverter type" air conditioner.
The compressor is mounted upstairs on the upper deck and the condenser is mounted in our "smallish" front berth. It works very well and is powered by shore power or an Inverter and 800amp hour batteries. It has a max current draw of 50 amps with a slow start.
The main use is to reduce the humidity with some cooling on a hot/wet night.

Now that sounds like a practical solution. Beau, may I ask what the Panasonic unit cost in AUS $$
