Poll Question:
Do you leave your marine A/C unit on all week while away from your boat? I shut mine off all the time when I leave the boat, but during these heat waves the inside of the boat is over 90 degrees when I get down on Friday. I was thinking about leaving on but turning up to around 80 degrees. My units the fans run all the time and the compressor kicks in and out as needed. I have tried leaving on the humidity setting but does not do enough.

I've been leaving mine on for years during extreme weather. I normally leave it around 80° to 85° so when I come down; the inside is not over 100°. This also makes it easier on my refrigerator

I adjust my SMX controls to change the frequency and runtime of the De-Hu mode to match the weather conditions, but THIS weather is extreme. It's gotta run nearly all the time to keep up.

I never did, I don't like the idea of a possible leak, but for the first time ever I left it in the HUM mode this week because the heat is like nothing we've had here in years, so it kicks in every 4 hrs for a half hour and until the temp drops by 2 degrees.

To me, high temp is 78*F, which is about where it stays when I am away. The fridge stays cold and it is nice to come to the boat with no to little humidity. I know folks who button their boats up tight and shut down all electric except for the fridge to save money. To me, that is mildew waiting to happen. I figure I am either going to spend the money on electricity or cleaning supplies.

BTW, I leave the battery charger running as well as the fridge, but I don't "button" up the boat tight. I leave one porthole open on each side which allows air to move through. Never had any mildew and the cabing never feels all that hot when I come back.
And I don't do it to save money, I just like to close all the sea-cocks when I'm away, including the A/C one.
I'd probably do it differently if I were in the south... Though I'm pretty sure I'd go with a covered slip down there.

Hahaha. Yes we actually do get a lot of bad thunderstorms in the summer. In fact the past couple of weeks have been crazy, last week we had straight line winds with gusts in the 70mph range. For some reason, water never comes in my portholes even in strong storms. Must be good porthole design (they face slightly down as in most boats), good drip action happening from the hull/deck joint rather than water running down the side of the boat, plus maybe the proximity of boats and dense trees at my marina that mitigate the winds. IDK, but the water stays out.

I like what Ernesto does, me, its on 24/7 from the time the boat goes in till the time it is hauled. Early in the season and late in the season I have it set in the humidity mode, rest of the season I have it set at 75 degrees.
I hear those that close all sea cocks, me I don't, I do exercise them though. I inspect my hoses every time I am in the bilge and have changed them when I see signs of wear, IMHO, if you properly maintain your boat and are on top of it, there is very little chance of a leak.
Also, I have a lot of wood in my boat, lots of glued molding, heat, humidity, and wood is not a good mix. Electronics like routers, tv's, satellite boxes, DVR, etc also like an environment that is stable. Also I think it also depends on what model boat you have, my boat being a fly bridge boat has lots of big windows, unlike my Searay I had. My salon can get real hot, even with the tinted windows, shades, and cover on the front window.

Also,
Having the Ac running all the time you are less likely to develop growth in the AC lines and unit. The flip side to that is (where I boat) you need to clean the strainers more often.

Actually you are more likely to develop growth in the lines and sometimes the coils. Because you are circulating nice clean water with food in it through the system.

I thought having water always moving would not allow attachment and therefore no growth. Kinda like not using your boat or running it. Is this your opinion or do you have fact to back up what you are saying? In my case, it was simply my opinion.
Thanks

I think Bill might be right on that point. The "critters" that are in the lines will die if the water flow stops. But keep the flow going and they will get food and grow.
As for me, I shut mine off. I have a friend who's boat caught on fire when their a/c burned up (they were near the boat in time, saw the smoke, and put the fire out). My catamaran came with a forced air system that draws cooler air up from under the boat (between the hulls) so I do run that in the summer plus an exhaust fan to help pull the hot air out. Since I've done that I've never seen it over 100 in the cabin which ain't going to hurt anything. The refrigerator and freezer do work harder, but they seem to put up with it.

The great thing about this site is being able to learn. "The "critters" that are in the lines will die if the water flow stops. But keep the flow going and they will get food and grow."
If they can't attach, due to flow, how can they grow??? Attachment makes a home, flow does not allow attachment, sh-t in sh-t out.

I can only get to the boat on weekends so I never leave mine running. I just received an email from my marina today about this very subject. It stated:
"It has been brought to our attention that many boat owners are leaving the air conditioning running on their boats while they are not on the vessel. This is against harbor policy. Heat and A/C units can only be run off harbor electrical while the boat owners is actually present on the boat. The constant use of these AC units causes power outages in the harbor and then other customers loose power to refrigerators and chargers. We will be doing daily checks of the marina and we ask that all AC units be turned off while you are away from your boat."

Sounds to me like you are over "marina'd" or underpowered. Same problem at my marina on weekends when the place is packed.

I suppose that there probably is no harm in leaving it on, and the electric bill is not really a factor because I wind up paying the basic rate most of the time anyway, but I just can't warm up to the idea of having water pump in to my boat when I'm not around, so I turn it off.
But, I have an express style boat and I keep the cabin very dark with the hatches covered when I'm not around so mold is not a problem in there. The AC also cools the relatively small cabin down very quickly, so it's not too bad.
If I had a cabin with big windows that let a lot of sunlight in I would probably be more inclined to leave it on.

The control head should have a mode selection button. You simply select "dehumidify" and the unit will come on every four hours and run until a half hour has elapsed or the temperature has dropped two degrees (°F, that is) which ever comes first.
If there no selection, then the function is not part of your units brain.

Our marina is in the process of resolving the question of leaving the air conditioning running (or heat or lights, et cetera) by metering every slip. Use it? Pay for it. Waste your own money.
This was precipitated, I heard, by the presentation of a recent electric bill which exceeded the annual budget and we're just starting the season.

That's not actually true. The "dehumidify" button came WAY after the functionality. CruiseAir SMX controls have all sorts of user adjustments, but because it's not intiutive, many owners don't know about them. The "dehimidify" function on a SMX is activated by simultaniously pressing "HEAT", "COOL" & "FAN". The display will blink: "HU"
Other useful adjustments of the older SMX's include the dimming of the display LED's, adjustment of fan speed (to make low even lower for example) and changing of the runtime and duration of compressor cycles in HU mode.
The SMX manual is available in PDF format on the Dometic website.
MarineAir also produced control pads that offered a dehumification mode without a specifically labeled key.

MarineAir refers to the dehumidification mode as "moisture mode". Moisture Mode in the older digital controllers is activated while the unit is ON. Simultaneously press the PWR and the DOWN button.
Older digital MarinaAir units are also programmable and the manuals are found on the Dometic site as well.

I use that "moisture mode" when temps are in the 80's or less. When it gets into the 90's my cabin is like an oven & moisture mode just doesnt cut it. Then I put the a/c on but I set at 80-84. It makes a huge difference & I don't have to worry about my refrig frying.

I leave mine on humidity setting during the week when not on boat. Run AC 100% of the time on weekends at dock or on generator. Not only for temperature but to keep the cabin dry. Rather not have a boat that smells like a boat, if I can help it.
