Thanks....I was almost getting ready to run the AC with the heater in
desperation...on way to Lowe's now to see what they have in stock...


If you are in a marina with no metered power....why not? That will cause
the AC to run and dehumidify the house. Commercial air conditioning
systems have heating elements in them to do just what you were
thinking....making the AC run to pump out the water.

I used to work in a shipboard calibration lab where the temperature was 72F
+/- .2 degrees. The humidity control to hold humidity to 50%, eliminating
the problems associated with static electricity, was steam heating
radiators built into the 25 ton air conditioning system. When the humidity
sensors said it was too moist, the steam came on, heating up the air
conditioner's output and making it run longer to keep up. This dried out
the air and shut the steam back off.

Of course, you'll want to make sure you have sufficient amperes to run them
both. Leave the heater on 1000 watts and turn the thermostat to way above
the normal setting. Run the AC and it'll pump out the heat and water.
Problem solved. The humidifier is the slicker way to do it. The hot
condensor heat the AC pumps overboard is simply reheating the cold air
coming out of the evaporator on a dehumidifier. Dehumidifiers heat the air
because you're adding the power of running its machinery and fan into the
net-neutral heat of evaporator and condensor.

I'm watching a mother laying dead on a stretcher next to her two dead
children as her husband screams in horror over the three corpses as the
United States/Iwraeli genocide continues. The USA blocked the UN from
condemning Israeli genocide this morning.

Damn them all....Damn US.

Damn the British Government for 1948.

We're having some problems with damp seeping in. Both the v-berth and the
aft cabin have wood bins on the sides for storage...these are open and
about 9 inches deep. That's where we store our clothes. The hull side and
bottoms are carpeted with the same fabric as the the liner, a sort of
nubbly burlappy material but more closely woven. It seems the clothes on
the bottom are always damp. I've been rotating them so they won't mildew
but that's getting tedious. Also have damp problems where the cushions
meet the hull walls in the berths. Got some roll out thick paper stuff
from West Marine but as soon as it gets damp, the sheets start picking up
moisture again. I've taken to running fans all the time to keep air
circulating and am cutting back on boiling anything or running the heater
excessively when it's raining so humidity doesn't build up. I've got 3M
window plastic over the ports and the vents are all open and drawing.
Thought of using DampRid, but since NC is in a permanent state of humid,
we'd be going through one of those every other day. Any suggestions on how
to keep damp and mildew from forming (except stopping breathing
processes)?


Hi Katy! I hope all is well! As others suggested a dehumidifier works great.
I don't have much of a problem with dampness during the summer months, but
I've noticed minor problems with the weather cools. I've going to get one
myself after I haul in February.

Hey Jon...al's well...went shopping for one this afternoon but
WallyWorld said they were out of season(Like it's ever dry in coastal
NC????) and all Lowe's had was some big honkin ones that were bigger
than our water heater...and of the drawer type. So I'm going to see what
Defender's and Sear's have. Yesah, summer isn't a problem...the AC takes
care of it and I just let drain down the scuppers..

You're getting condensation. The only thing that will work is
reducing the humidity level of the interior air in the boat. An
electric heater paired with a dehumidifier is probably the most
effective. We sometimes run an electric heater with the air
conditioning which accomplishes the same thing.


That was going to be the next step...we run two heaters, one in the aft
cabin and one in the salon...if I can't find a dehumidifier fast enough
I'll just haul that out and see if it works with the heater's/. Another
liveaboard was complaining too b ut they have propane heat and theur
cabin was actually "raining" on them. At least we don't have that going
on! The hatches are staying dry and there's no condensation on the lexan.

inside the boat is DRY, not like a North Carolina swamp.

Out of interest, is it possible to keep the air in a boat dry? OK, if
you've got a de-humidifier running 24/7, and the boat is closed up then,
yep, I expect it'll dry out, but what about a boat that's used
regularly? Can you ever dry it out?

If you are going to use the AC to dehumidify use a low air flow rate
setting, if possible or restrict it, to keep the evaporator
temperature low. It will produce a lower humidity and probably remove
water faster that way.

Thanks. Will keep that it mind.

Katy,
You are not going to like my advice, but the problem you are facing is that
your hull is not insulated and has become a cold sink creating condensation.
For your information, this is what kills steel vessels, as it creates
corrosion in those places you do not have access to. The correct solution is
to insulate the hull with Urethane foam and then paint the foam with a fire
retardent latex paint. This will prevent the moist air from condensing on
the cold hull. Insulation without an air barrier is insufficient. A
dehumidifier is a band aid. It will help, but will not resolve the problem.
Of course this task should have been done before the interior was installed,
but then the cost would have made the boat less competitive for sale and
this problem would never be the builder's in any case. I have suggested
Urethane foam, but other products perform as well, like sprayed cork, but
they are not better or less expensive.

Well...since the boat was not ever buiolt to be a li veaboard, I suppose
the manufacturer would have considered that superfluous...we have a 31'
Kirie Elite and you're right...there ain't much between us and the deep
blue...I have noticed that the prpoblem does not occur in the bins
behind the settees which have slatted wood instead of material next to
the hull....We're not getting condensation anywhere else except in the
closed areas (it's a fiberglass boat BTW, so no fear on the steel boat
thing)...The head liner seems to provide enough insulation that we don't
get ceiling moisture...but the foam insulation is an idea...the liner in
the berths needs to be replaced and that time would be good to do
something like that...ah...another boat project...yay...but since we
will be living aboard every winter we'll need to do something
efficient...thanks...

If you don't mind shopping on-line, google for "mini dehumidifier".

(I got mine at a local marine store...)

You are living in a damp atmosphere, sort of like a swamp. The only
solution is to install an air conditioner or dehumidifier or move to a
drier climate.
