Cover for a Carry-On air conditioner
Hi, I bought a second hand carry-on Air Conditioner for my sailboat. Unfortunately it did not come with the cover that goes over it when it
is placed in the hatch. Does anyone know if there are companies making
these covers or where one can buy the pattern. They can be bought at
West Marine but the cost is around $250 which seems way out of line for
a canvas cover. Thanks

It seems strictly for dockside use, although I just acquired a Xantrex RS 2000 inverter that could probably handle it offshore at the cost of beating up even an expanded battery bank. It eats up a good portion of the starboard pilothouse locker, and while I would have preferred the stowage, I suspect I will just leave it in there for the odd tropical dock we choose to pay for. I don't have A/C at home (very old hot-water heated rad system) and I don't work in an office, so heat doesn't bother me as much as some.
Our layout is as follows: we have an aft cabin, a forward saloon and a pilothouse. There are proper vents and returns in all three. With the boat's stern facing south in a Toronto summer (32 C or 90 F) and with all hatches closed, I got the saloon and the aft cabin to about 23 C/76 F in about an hour. The pilothouse (aka "the greenhouse") was a broiling 37 C/99 F. No dice there. I ended up cracking the pilothouse hatches just to let the hot air rise.
The water filter/strainer is accessible and I can winterize from a central standpipe. I only used the heat option once because the boat is usually warm enough due to insulation to the water line and candles/lamps/body heat. I have also heard of the 40 F water limitation, along the previous owner (who lived aboard in a Toronto winter...a real one, not this tropical '06-'07..with bubblers) made provision for a second 30 amp shore power line (total: 60 amps). While I got the impression that he needed this extra to run the Marine Air unit in times of cold, maybe he just needed to run three ceramic heater cubes or a heat fan...I'll have to check.
A friend put a small Mermaid A/C in the wet locker of a Viking 33, which is a smaller boat than yours, I believe, and he loves it.
Or rather, he could care less, but his wife and daughters demanded it.

As you are sailing in Lake Huron you will might want the heat more than the air. Season is relative to the sailor. Water temps will be low to mid 40's in April (really want that heater at night), warming to mid to high 60's in July, staying in the 60's most of the way through September, and then back to the high 40's by the end of October or early November. Good Luck.

The heat function is really nothing more than the same concept as a heat pump on your house. It really works well, but is not quite as efficent as the Air Conditioning. Water temperature will play a factor, but I cannot comment what will happen when it gets really cold because the coldest I have used it is probably in the upper 40s (water temperature, not outside temp. Have used in the 20s outside).
You will like it. I have heard conflicting comments on the Mermaid, but most of the negatives were on their small models they sold several years ago. I have no info for you on a 16k so would take the comments posted above as true.
Another suggestion for you: Put a collection pan for condensation to pump overboard versus dumping it in your bilge (like most people do). This keeps the bilge dry (in theory, I guess). You also get a lot of algae buildup otherwise. Don't forget to really oversize the strainer and make it very accesible.
Take care. Hope it works out.

You need to wire in a SHore/Gen/Off Switch. You switch between the two power sources.
Here is an example (and the one I use):
PS Essman, I am suprised you do not have one already.

Air Conditioner Wiring
Read through this thread and have a question.
If I wire the Air Conditioner to a separate AC service, with it's own breaker, how do I wire it so that it then runs from the generator? The gen only feeds one service.

|CaptDaveB||Mermaid Marine air is the only manufacturer to offer a 5 year warranty and prettty decent prices. The pumps they offer are pretty slack, but otherwise they have good units. Their 16.500 with a proper installation would be more than enough for you 34.|

|1970Columbia34||Ok we are looking and leaning towards the mermaid 16.5k with reverse cycle heat. How does the reverse cycle heat work and should I worry about the water temp? We are sailing in lake Huron and I have no idea what the water temps get down to during the sailing season.|

|S/VNirvana||I brought back the carry on a/c from Boat/US. Did not cool off the interior. I went to an R/V dealer and picked up a Carrier a/c unit and placed it into the galley hatch of my Pearson 36. The hull is dark blue and gets very hot in the summer, no shade. It just drops into the hatch and I keep it in all of the time. Works of the dock 110V via and extension cord.|
