Aside from the potential safety issues of blocking the entrance, there is one more operational issue to keep in mind. In the bottom of all window AC units is a small diameter copper high pressure gas line that wants to hit the water in the pan before seeing the condensor coil to get maximum performance. It the unit is not level, the water may not be high enough to precool the hot high pressure gas line. Under this condition, about 60 - 80% of the cooling capacity is lost! Remember that dry is more important than cool, so the slower the fan runs, the colder the evaporator coil gets and thus the more drying that you will get. Also, consider that a small AC unit will come on and run, thus drying over long periods. A large unit comes on, quickly cools and shuts off and the drying is off as well. This situation means cool but clamy and is not comfortable.
BRILLIANT BRILLIANT BRILLIANT. You are so smart. Mac Gregor, no marina slip fees every month, sail or ski. now A/C ...a man after my own heart. Beating the system in every way. Thanks so much for sharing.
I am in the process of adding AC to our 2005 26M. If you go to the Macgregor sailors site you can see a mod where the unit is offset in the companion way so that a piece of the plywood frame can be removed to give easier access to the cabin. Regarding the back of the unit, I used hardware cloth cut to size and just screwed it onto the back. Or duct tape...... Nice site!
Thanks for the video, that looks like a lot of work to have to move the a/c. My 26x had a nice companion way a/c box made out of starboard so it can be stepped on and does not require moving. It looks like it would fit the 26m. The only down side is when you step in you step above the ladder but I've gotten use to it. I need to get that generator gas extender for my pulsar 2200. That is a super mod for Florida heat.
I do this on my Sailboat. If you stick a small section of paper towel in the back on the lower lip it will wick the water out so when you pick it up it won't dump water everywhere. I just bought a 8000 btu portable air conditioner for my 25 foot Cabin Cruiser and it works sweet.
We put our 2000 watt generator in the dinghy and tie it off about 5 feet from the boat. This allows the exhaust to be further from our boat, plus it's extremely quiet then. We sleep under the cockpit and we still can't hear the generator at all, and definitely no vibration. We still use carbon monoxide detectors just in case.
I haven't any need of A/C during the night (sun goes down, we cool right off), but to seal the top of my homemade bug screened companionway panel, I use one of the Home Depot poly foam 1" pipe insulation sleeves with the split the length of it. It's easily cut to fit and when fitted down over the top of the hatch board the sliding hatch seals nicely including the spaces at the top corners
we added a portable ac inside , we dont have to manage with the door ac, but we need to take care of some water especially at dehumidify mode, so we drain it into the ballast or simply outside. we use the ballast as shower water and replace with either rain or marina water also. some bleach needed to keep it clean. we have a 26x, so we sleep in the vbirth , and removed the table for creating a living room area. we eat in cockpit or on top small ice box between sofas ...
we have a Mac 22, just starting out so if we like sailing we are going to get a 26 m. seems a perfect compromise for our needs. we don't want to cross oceans and don't want to be stuck to one port. love your videos. id rather see videos of people with boats 28 foot or under, I love the ingenuity it takes to have a smaller boat. keep the videos coming.
you prolly dont care but does someone know of a method to log back into an instagram account..? I was stupid lost the login password. I would love any tricks you can offer me
@Kabir Phillip I really appreciate your reply. I found the site thru google and Im trying it out atm. Takes a while so I will reply here later when my account password hopefully is recovered.
My birthday was on AUG 13th. This video was a great Bday present. Thanks. The NEXT thing is to eliminate your gas engine and replace it with a high-end trolling motor. I plan on buying 6 deep cell batteries for my boat and a honda generator like you have...along with your add gas attachment. an extra back up trolling motor only costs $90 and will push my 27ft sailboat at about 5 knots or more. simply put it on a dingy and you have that motorized too. When not using any of the batteries, run the generator to charge the batteries...IF you don't have solar or a water generator. :)
Do you find any problems with your Honda generator getting wet out with either seawater or rain? Wanting to do a similar setup but need your suggestions! Happy sailing!
I have a similar setup and camp on my boat quite frequently. Even if it's a pain in the ass it's still worth it to have ac lol. If it were me I would probably make it so the door an ac swing open together because that stepping way over it would get old quick. plus if u had guest on your boat would be less chance for them to screw something up.
I did the same thing, but i didn't want my generator getting rotted from the salt air or even stolen by a random pirate, so put it in the cabin with me. I didn't need an extension cord. All you need is aspirin for the headaches and your all set
I am not all that knowledgeable with ac's but those small units should be redesign able so they would fit into a hatch way and blow down. Did you ever look into that?
For the guard on the A/C unit you can use the existing 4 screws in the back with some plumber strap. And loop it through the guard to the screw below. Or keep using duct tape also works. Scott Gorges Oceanside, Ca
Or take one of he Screws out, get Stainless Screws a bit longer, and Fender Washers between the washers and the Grate so no Vibration can make it noisy!
Im mow lawns all day standing 1 foot away from the exhaust for hours, 5 days a week. Its comical reading the comments how hes going to get carbon monoxide poisoning.
Billy Box mod is better...The AC unit does not have to be moved, it creates another seat in cockpit, and you don't have to keep putting it in and out.... I have the Billy Box on our 26X. Where do you stow the AC when your not using it?
Looks like the billy box works better for the 26x, the 26m has a smaller companion way and already has a seat in front. We keep the AC in the vberth. It only takes two minutes to setup and take down, so it doesn't bother us. The 26m cockpit is small so rather have the room.
how do you avoid exhaust fumes from getting into the cabin downwind? we tried a similar setup with a generator on the bow (not for AC) and the fumes / smell came into the cabin. This is also a carbon monoxide danger obviously. We ended up hauling the genny on davits above the transom. It was more noise but no fumes after that.
we are considering either a yamaha , honda or brigg 2000. brilliant idea for extra gas , i'll check with eBay guy for another brand of cap. that would work for extra 50hp motor gas ... but we get great mileage 5 gal for 7 hrs at 8 knots ... varies with windage, better or less.
I'm not familiar with the Macgregor 26 but isn't there another hatch somewhere that you could build an air conditioner duct into so that you wouldn't have to barricade yourself at the main passageway? Maybe in a cockpit bench or forward locker?
yes, you could put it in the front hatch. we tried that on the last boat but decided this method was more efficient for cooling the boat. Also, we would rather separate the generator and AC and we sleep in back so rather not have generator vibration overhead. We usually just put AC in before bed and out in the morning, so not like we are crawling over it a lot.
so how many cans of gasoline do you go through a week and thus have to store your own private gas station on the boat? Seems easier to just by a diesel generator and feed out of the boats main engine fuel tank. Also having a generator and gas can just sitting there on the bow of the boat isn't going to work to well in a storm. And when the cabin humidity goes up during the storm it would be nice to be able to run the generator for the AC
With the generator in the bow, aren't the fumes blowing back to the cockpit? I like your exhaust extension. Do you use carbon monoxide alarms? Thanks for the explanation of the auxilary tank attachment. I have been meaning to order that from your store link since I heard about it. (I was outside of the US at the time otherwise I would have gotten it immediately. :))
We only run the generator when we are in the cabin. It is only needed for the AC as we have plenty of battery power for other needs. But even when it is running, we rarely notice any fumes as it dissipates by the time it moves down the boat. We run two CO alarms, one with a digital display, no problems. The exhaust extension also helps to push it down to water level. We just welded a threaded nipple to the exhaust, then made up an extension out of high temp pipe.
Wow, good point, been using it this way for six years and never occurred to me. I guess I don't think enough like a thief. I will add a security strap on the front of the AC. Thanks.
We do not notice any generator fumes. I got a threaded nipple welded to the exhaust and we attach an exhaust extension pipe that runs down to the water. But we often do not use it and still no fumes. We also have two CO detectors in the boat for safety.
@@SOLDOZER I was replying that the Exhaust should be directed into the water, to hopefully divert the emissions, and I suggest a co2 Alarm in the Cabin as well, That is certainly what I shall do in my setup! I did appreciate them putting the Vid up, as well. My Mac 26X will be cooler, anyway! :)
i would have got the portable ac that has duct work so you could have put the air in the cabin and ran the duct to one of the hatches, those window ac units need to be leveled for best efficiency.
just an idea but instead of the foam how about some of that split foam pipe wrap used to winterize home pipes. Hell...even an old water noodle split with a razor blade would work.
maybe you should look into a solar panel aircon setup i bet you save alot of fuel costs in the end. sun put out alot of power with todays solar panels and we starting to use power saving inverter air cons that run off less power then the old ones do cost to run maybe a good 12v fridge compressor can cool a plate and a 12v fan to run maybe it be good to try water temp a small water pump to a radiator core and a 12v fan on the core may just do the job fine but thanks for your video good to see how people do it same times you lean alot on some video's i did know about the kit to run the generator longer so there you got thanks mate and have a good one.
We have considered adding a solar panel to run a 12v refrigerator, but we are rarely away from ice supply long enough to justify the cost and maintenance. We only run the air conditioner on generator about 20 nights a year so that is about 20 gallons of gas a year. I have yet to see a boat with enough solar and batteries to run an AC. Maybe technology will get there someday.

Thanks for the video. We use a similar 5000 BTU generator in the hatchway but put our Yamaha 2000 ie gen. On a platform I constructed in front of the motor. This protects the gen., clears the deck and puts the exhaust out the back. We have some sleeping in the bow so no noise for them. www.macgregorsailors.com/modt/index.php?view=2019 can also be used while motoring and can attach to main fuel tanks easily.
Nice setup, I have seen others set it on a rear platform. We really never notice the generator fumes as we are not in the cockpit while it or the AC is running.
Nice boat, I also have a Macgregor 26m, I want to power sail from Florida to the Bahamas next summer. I like to if possible to go over in a group or with another boat.
While I do appreciate the ingenuity of this set up and the low cost, there are many ways this could go very wrong. You also have a terrible seal around the hatch and the a/c cutout. At least seal the perimeter of the a/c unit to the hatch board. It is your boat, no argument there. Good luck.

While I appreciate the idea .. the supreme disregard for safety in evidence here is alarming. Shock hazard, carbon monoxide danger is extreme !.. sorry. This can be adapted ... but not in this way !
There is 5 to 10 cm between the sliding hatch and the plate over the ac. So if you lock it from the inside it will take 3 seconds to unlock it from the outside. So this "lock" is not even close to adding any protection. The ac system itself is nice but even not in use will still take up space on the boat. Why not put it somewhere where it can stay, is out of the way and can be used when in this spot?
Aside from the potential safety issues of blocking the entrance, there is one more operational issue to keep in mind.

Do you strap a carbon monoxide detector to your face when you mow the lawn too?
Omg thanks for suggesting i have ac in my companion and a bag tapped up lol😂 but that gen is so annoying
For $499 you can get an rv rooftop ac 13.5k btu. Mount on the bow below the cockpit.

Nice work. I really enjoyed the video. It was very useful not just for macgregor owners
Practical and relatively inexpensive. Thank you!
Glad I found your channel. Just looking for a McGregor for basing in Brittany. Aircon/dehumidifier is an excellent idea.
Thanks!
they are a fun boat, good luck on your search.
I love it...but a locking latch is useless. You can just pust the aircon into the boat.
Wow, good point, been using it this way for six years and never occurred to me. I guess I don't think enough like a thief. I will add a security strap on the front of the AC. Thanks.

Thumbs up!
Use Velcro for back grate
good video
I would have made it the same way,but would have made it look a little less trashy,,,, but I suppose it works
Good video! I wish I could talk you into Lowe's over that other store. :)
how do you avoid carbon monoxide poisoning?
While I do appreciate the ingenuity of this set up and the low cost, there are many ways this could go very wrong. You also have a terrible seal around the hatch and the a/c cutout. At least seal the perimeter of the a/c unit to the hatch board. It is your boat, no argument there. Good luck.
Poor guy lol but he's cool! 😆 😎
Pretty rough set up.
duct tape is perfect..even nasa uses it
we have additional auxiliary tanks for our generators..takes a minute to swap them out
love your joke :)
that is and accident waiting to happen , getting in and out of the cabin...
It isn't that bad, of a stretch getting in and out with this setup, actually! If there were a Lot of Wave action, I wouldn't! Otherwise it is just fine! I own a Mac 26X, and crawl over my rear Hatch all the time, if needed!
Nice Hack!
