We rigged up something in the front window for it and it really made life bearable during the hot humid summer. (Again, not useful if you are anchoring out) Sometimes we just set it up on the floor of the cockpit and it still helped quite a bit. Yes, we looked a bit ridiculous but it worked. ...
I used to boat in the mid Atlantic region. An AC unit is pretty much mandatory in the summer there. We also used it on the Erie Canal in late Aug. and September. I have a window AC unit that goes in the center window and a fan that blows the cool air from the cabin into the v-berth. This works quite well. A small Honda generator (EU1000) on the swim step is quite capable of running this AC unit when shore power is not available. Having an extended run tank for the generator is also handy.
Only disadvantage to the window AC is that you can't really drive the boat any distance or at speed while it is in the window.
