I have a *real* boat AC. The one that fits over a hatch. I like it, but it is heavy 50# and awkward. Needs a substantial Generator to run (I run it from dock power).
My wife *okayed* the purchase.
She was the one that wanted it.
I think it is a pain, I do not wish to leave it around when I am not there or on the boat..as it is about 500$ and a sailboat locks are not known to keep anything but honest people out.
However, it does take 100F heat and drop it down to 82F but most importantly it does make a big diff on the humidity.
Oddly enough, moving from a cement dock marina to a Tyvek dock made the most difference.
Not worth for a guy (in my opinion..I will just sail out until we get out of the "land effect heat".) However, from male/female relationship aspect DO IT!...
Well worth it. My wife actually comes to the Marina now.....
Good idea or bad idea... 'Not saying!
