Ok Phil, help me out here. My wife is on me about "why nots" when it applies to mounting in the galley wall. My question is how will we vent the heat out of that compartment? Back to an original question, could we store, say, a Honda 2000 in the anchor locker providing it is secure? then bring it out to the bow pulpit when we want to run AC while bobbin and burnin on the lake. Again, this may not be feasible, and yes, this would not apply for offshore use, but many of us are lakebound for the near future.
Lakebound here too, 'cept I am garage bound since there is not much lake at the moment....
'wreck, I see several options for removing the heat. Simply lifting the cockpit hatch would be one... Some fore-and aft pointing clamshell vents would keep air moving in there too. One could consider an active system, like with the bilge blower, although that will require current from the DC side.
As for running an AC off of a generator, one needs to consider the surge current of the compressor's AC motor starting. Whatever generator you have needs to be able to supply this peak demand, otherwise you will burn up the compressor, the generator, or both.
I think it feasible, and still an option for me to consider, but don't rule out the ice-powered cooling while on the hook. To me both units are part of a total engineered system. The AC powered AC for the dock where shore power is available, and then the ice/fluid/heat exchanger unit operating on DC to maintain temp...
