I got the ultra-quiet Honda genny (EU2000). It's light and quiet and

no
problem with a 13,500 btu AC unit. A bit on the pricey side but a nice
addition. We only use it when anchored and extremely hot/humid. We
leave
the
cabin open as the cool air tends to lay down below, unless the
mosquitoes
are feeding. The AC is hardly noticeable tucked as far forward as can
be
(5000 btu).

many who have AC stay at the dock on hot days.

I did a long winded post about a year ago in which I detailed how I modified
a window unit (Wal-Mart 90 bucks) to make it a water cooled unit. 2 garden

works very much like the coolant system of a car. A small water pump forces
fresh, heated water through a hose to a coil of copper tubing (performs the
function of a radiator) which stows with the anchor when not in use, when in
use, it simply lays in the water, hung from the forward rail, to transfer
cabin heat to the bay water. the cooled water returns to a home-made
refrigerant (freon)-to-water heat exchanger. The condensate drains to my
bilge and is pumped out as needed. I saw somewhere else where someone was
talking about bleach in the bilge (and Martha Stewart) -er ah, I do that too
from time to time. It works well.
In all honesty, I'm too lazy to use it too often; only when I'm highly
motivated by discomfort to I use it.
Water cooled units are available commercially (they are used frequently in
commercial hvac work), but they can be pricey.
When I pulled into my slip in Beach Haven last summer, my closest neighbor
was a retired NASA engineer. The marina owner, who knew the engineer well,
asked me to time how long it took the engineer to ask "what the hell is that
thing." It took 3 minutes.

Scout,

Ole Thom

Thom,
AC ranks right up there with indoor plumbing and anti-biotics. No past king
or queen lived better than we in those regards.
I've spent most of my life in mechanical construction (steamfitter). It's
all about boiler rooms, city rooftops, and stifling mechanical rooms. In the
winter you freeze, in the summer, you sometimes work 'til you puke. On one
of those hot days I made a vow to myself to be cool and dry when I'm
relaxing. My next sailboat (it's gonna have to wait until I move next year)
will have a less obtrusive, factory designed unit. Until then this will have
to do. ahhhhhhhhhhhhhh

Scott - a question:
Right now my boat is trailerable in the Class C driving sense. If I wanted
to buy a bigger boat and transport it (using my CDL A lic), how big of a
boat would you say could be pulled with our Freightliner? I'm guessing the
height would be an issue before anything else. Still, If I found a boat that
was not in the area, I have access to the tractor and maybe could rent a
trailer to bring it home.
Just a idea - a' brewin' in me 'ead.

A friend made a particle board frame to hold a 5K BTU A/C in the companionway.
It was enough to chill the boat down on a hot night, but of course it was a pain
to get by. They gave it to me when they gave up dockside life - its in my guest
room now.

I suppose I wouldn't mind A/C but we lived without it while dockside in Florida
for 6 months (Winter, not Summer!).

I ran a length of 3/8" OD soft copper tubing inside 7/8" copper tubing. I
made a tight set of rows using 7/8" 90 deg copper elbows, so the outside of
the condenser is squarish. But, this made it extremely difficult to fish the
3/8 through it. If I were to make another, I would layout a straight length
of 7/8" soft tubing, then insert a slightly longer length of 3/8" soft
tubing inside the 7/8", then roll the whole thing into as tight a circle as
possible (no easy task either, but doable).
Solder a 7/8" copper tee on each end. The 3/8" tubing passes through the
tees at both ends, (either bush the 7/8" down to 3/8" or pinch and braze a
short 7/8 stub around the 3/8 for a water tight seal. The third tee opening
at each end is your fresh water inlet and outlet. I solder hose adapters on
here and this is where I connect the garden hoses. I put a Taco 007
circulating pump in series with the 7/8 tubing. The other end of both hoses
connects to a second coil of copper tubing. I used 5/8" her (M, or thin
copper for easier heat transfer). I formed mine into a rough triangle shape
so it would fit in the anchor locker, around the anchor, when not in use.
If you don't mind making (or buying) a new heat exchanger every year or so,
you could pump seawater through the exchanger. It does make the job a bit
simpler.
One end of the 3/8" tubing ends connect to the compressor discharge (outlet)
and the other end becomes attaches to the expansion device (probably a
capillary tube). Be sure to use a filter-drier between the 3/8 and the
capillary tubing.
Best practice is to pull the system into a vacuum before charging it with
refrigerant. I've it done plenty of times though, if you didn't have a
vacuum pump, that you could just purge the system with refrigerant to
displace the air. This works, but there are a few problems with it (e.g.,
it's illegal in the USA to purge refrigerant to the atmosphere, it shortens
the life of the system by not removing all the moisture and non-condensable
gases that are surely still present in the system).
I F'd up and let the water sit in mine all winter and of course the water
froze and damaged the tubing. I made it a lesson plan at school though; I
brought it in with my torch, then taught a quick lesson on brazing, and
turned it over to my 10th graders. They learned how to braze and I got my
system working again.
