One roll of aluminum tape does it.....fun to work with and hugs the closet wall so hardly no interference with the back shelving. I just built my own, will include pics later.

I'm just giving ya a hard time.

Did you do foam board around the stack?I thought the heat would be to much.

The foam board was aluminum coated, so no issue with the reverse heat. Home Depot had the round stack to rectangle adaptor, so I just made the duct to fit the adaptor. It was so easy (and fun), that I'm going to do the rest of the ducting with the same stuff. Stick-on insulation tape (also Home Depot) does a great job for insulating the adaptor. I also saved the thick insulation from the old round hose and have reused some of it. My whole system used the round accordion style hose with thick insulation right up to the registers. The flow was impeded by the turbulence inside of the hose, especially in bends. My A/C is old. It needs all the help it can get. Additionally, the unit was resonating the closet floor like a guitar. I cut two of those interlocking floor pads from Harbor Freight and rested the unit on top....now, no resonance. It's old, yeah, but maybe I can get a couple more years out of it. Unlike Bill's unit, the PO ran the duct ran right up the middle of the closet, making the space behind difficult to utilize.

Thanks for the information on the duct board Larry.
If I can locate one I'm thinking of replacing the metal outlet vent with a teak trimmed one with horizontal and vertical air direction blades. I think it would direct the air distribution better and with less turbulence. I discovered that a previous a/c installation used the stateroom hanging locker and a 12" x 12" return air vent was installed on the forward bulkhead at deck level. This vent lets us have the option of closing the stateroom door and still have return air to the unit thru the galley and hanging locker louvered doors.
The new Cruisaire 16K only weights about 65 lbs. and has built in vibration damping mounts to the deck. The condenser water overboard hose and thru hull in the photo was drilled at interior deck level and the coring is about 1/2" thick in that area of the hull for reference.

Gettin ready for new a/c this week

Velvet has a 16,000 a/c unit that is old. There is a company here in Stuart called Ocean Breeze a/c that make all kinds and I am going to get thier 18.500 unit which is just a tad bigger than my old unit which fits under the galley sink area. I pulled the unit and will bring it to them and they will match the fan exit so all I need to do is plug in the new one I hope. If not will have to get an electrician in. That should cool Velvet nicely.

Cool Beans has the original 1600 btu AC. We just installed a thermostat as this old AC didn't have one. It was either off or freeze your butt off cold.

Bill and Ben: Here's the photo of the rectangular ducting in my closet I promised you weeks ago. This shot is with the closet door removed. As you can see, it hugs the wall nicely, only takes maybe 2.25" or so. This photo was after finishing the cutting and tape of the duct board for the main vertical duct. The black accordion duct you see at the top left of the closet is now also the same stuff. Very easy and fun to work with. Getting to the shelves is much easier now.

Thanks.That really explains things.I'm looking to make my own ducts like this for a mobile home I have,instead of using insulated accordion type plastic ducts.I'll also consider using this in my boat as well.

I have one of their 16800 btu units and I really like it. I went with heat strip instead of the heat pump as I can run it on the hard or with the sea valve off. I also have a SeaBreeze unit (16k btu) for the front of the boat that is a heat pump.

I am very impressed with the Ocean Breeze company , have you been to their shop?

Thanks Larry, the duct board looks great and I can see how it opens up the closet shelving I will add it to my work list.

What Marina are you camped-out at, Capt. Craig? I usually have to make runs to Stuart every time I go to Indiantown.

My location in Stuart

Hi, My boat is at my home, directions are easy. Just stay on sr76/martin grade which turns into Indian ST. when you cross the new bridge. Stay on indian st. to my home. Once you cross us1, then rr tracks, then dixie hwy, and continue east until you cross a flat bridge, once you cross that bridge the name of the road changes into St Lucie Blv. so, two blocks past that bridge on your right you will see a tall white pineapple post mailbox, that is me. 2513 se st. lucie bl. 772-341-0393 Cpt.Craig
