Marine Air Conditioning

(1/2) > >>

Captain Bri:
We have been living aboard doing projects and of course it is hot in the south!  We started looking at Marine A/C units and were wondering if anyone has A/C installed on their P323.  If so where is your unit located and how many BTU is recommended?

We have tested a 5K BTU window air conditioner and it did fine in cooling the main cabin, perhaps a marine unit of this size would be adequate.  We are considering a Webasto model that Defender has on sale, which also provides heating.  We are looking at a space in the head where the vanity sink used to be.

Knosaj:
not sur eof the BTU, i can check when I am down there next time.

Our unit is located directly across from the head, in the small locker. th eonly vent comes out on the wooden wall, err, bulkhead, whatever, on the port side.

at this time, it only runs on shore power, but keeps things frosty when at dock on hot summer days.

i am thinking of rigging up some type of ginny so that we can also use it at anchor.

Captain Bri:
Thanks for the feedback.  I take back my comment that the companionway A/C did fine -- it did not!. As the hot spell continued last summer we could not get the temp much below 80 at night.  We plan to move the boat to Florida but may find ourselves on a mooring so the project is on hold.

lauderboy:
I'd also like to know how much BTU you have for your AC. Right now I'm using a carry-on AC that's 7k BTU and it really not enough.

Other question though. Is that AC running off your main 30 amp shore power or did you have to upgrade it as well?

Rayallyn:
I have a 5K carry on unit that is set up through the main cabin hatch and it got in the high 90's last summer here in Marathon Florida. If you set up shade over the cabin and deck this helps tremendously. I have thought about a marine air conditioning system but with the space and air ducts that are needed I've decided against it; besides, I have a lot of other upgrades to do.
