i didnt find a need for air conditioniong in fla or in louisiana in summers.... notuntil i go tto mazatlan and experienced 110 f heat with high humidity.
then i chose to buy a window unit instead of marine unit as they are much more efficient. no one mentions the efficiency, just the UGLINESS of having a window unit , which is easily dispo´d when not desired....
besides, a window unit, when installed properly, is no uglier than the lump of stuff marine units plop over a hatch or the disruption in your interior as it is installed and the question of what to do when it breaks..which it will...loli have much easier repairs
...pitch and rebuy... and i have a nice protective frame for it and formosa
windows..easy in easy out...then i can SAIL without it, and i can do with or with out the machine,and it stows easily beneath my bunk.
i gave this problem much thought before buying
fo r140 usd a window unit, instead of paying multiple thousands and then paying for install....
