53MY 1981 Air Conditioning

[Dragonten]

I am looking to get air conditioning to my enclosed back deck area. Right now I have air in the salon with the blower on the rear starboard side of the salon. It pulls air from the back deck area to feed the salon. Trying to figure out the easiest way to get cold air to that back section. Has anyone done it? I was thinking maybe to upgrade the size of the chiller and blower, but not sure how to get the air blowing into that area.

Many with the aft hard enclosure have a separate unit on the back deck in a cabinet under the ladder.

Are you sure your aft salon unit is pulling hot humid air from the outside ? Never seen that

It s going to take a big separate unit to cool the aft deck due to all the glass area and volume. At least 32k btu. 53s came with two 16k for the salon which is about the same volume but with much better insulation

Now that I think about it the blower pulls air from the salon not the enclosure area. I have a diesel heater that blows hot air into the enclosure when its cool and the vent is near the ladder area.

How do they get lines to a unit under the ladder? I was thinking of somehow getting a blower with two air outlets, upgrade the salon unit and try to use it for both areas. Or find a way to split the airflow to both areas.

The ac unit for our aft deck is located under the fly bridge u-shaped settee. Not sure the BTU's, I can look next week if you'd like. It's a game changer for those cold mornings under the frozen north as SB put it.

I just have a bench on my flybridge and behind it is the crane and dinghy that sit above the aft area. I would not want to cut a hole in the ceiling.

One option you may look into is a portable AC unit. We ended up with one in our salon on Pau Hana while recovering from the $$ hit of replacing the lower deck AC units (3 new units) in the first year. We kept the salon at 72 degrees with a 12K BTU unit from Home Depot, and it didn't hit the electrical consumption significantly according to the bill. While it was intended as a temporary solution, another suggestion from another boater in the marina was one of the mini-split standalone units if you have a place to mount the inside and outside pieces. Theirs was mounted on the flybridge for the outside piece, with the inside piece hung from the overhead.

Under that bench is where the air handler is for our aft deck ac. There is a hole cut in the flybridge sole for the ducting.
