In the cockpit there's a seat/hatch that opens up and I prop it open to exhaust the hot air.

Where does the hot exhaust air go? If the quarter birth was too small to use, then this sounds like a good use of the space. If you don't have the exhaust piped out, you might get better efficiency if you can get a vent out somehow.

On those 100 deg. days, a tremendous amount of heat radiates through the coach roof and portlights. A boom tent can help shade those areas and prevent the heat from migrating into the boat.

Thanks for the insight on the condensation disappearance. FYI, the A/C was just thru the same heatwave you have been in and it didn't show any condensate so I guess it is working even in the extreme HHH.

If I had the expertise that you have I possibly would have taken apart the unit into components that I could fit in more readily, but I am not that knowledgeable.



I am a member of the Bristol Yacht Club but I have the boat in Somers Point for the season... I needed to sail where I can really sail...

Last summer I chartered a Jeanneau 39 and toured the Chesapeake. It was also as hot then as it has been now.

Do you still have sailboat races on Tuesday Nights at Anchor?

Also, I have shot some sailboat tours at the Annapokis Sailboat Show and you can see them at Sailboat Video Home if you would like to take a peek.

Thanks again,

Hey Bruce,
Yes that is the East End Yacht Club that Races. They are always looking for crew. Most of the members are members of Anchor too. I don't race myself.

The A/C cools great at night... During the daytime it really only makes a dent in the heat but it is better than it was... If you get a higher BTU unit it will be better for the daytime heat... I used a 5000 BTU... Since there is no room for a generator anyway, cooling while underway wasn't really a consideration anyway.

Window units use a ring around the condenser fan that picks up the condensate water and "slings" it onto the coils where it evaporates and helps improve the efficiency of the unit. They may still make enough water to need a drain in HHH weather. good luck!

Re: Your thoughts on my A/C install plan/Mac25 1984

The project has been completed. Just in time for the 100 degree weather last week. It was a 5000 btu unit and it works great at night. During the day it really can't keep up with the 90 -100 degree weather and i didn't expect it to. But in the evening, it worked like a charm.

I bought a Haier unit (99 bucks), made in China like everything else we buy. For some reason, there is no condensate to drain away. Although I was ready with a liner, tube, drill and grommet, it appears it is unneeded. I assume the condensate evaporates away during use. I didn't need to drill through the Lazerette (although on my vintage 1984 m25 it can only be used for storage anyway) into the bilge for the condensation.

It is located on the Starboard side flush with the bulkhead. I tried to seal the area off with styrofoam bit it was too thin to really handle and I scrapped the window shade idea (no insulation properities). I used some dense foam material that a kind gentleman at a packaging company donated to the cause. It was 100 degrees that day and he was a boat owner too. Also, I must have looked pathetic.

So, I was able to get cool on the cheap. I would have used a stand up model for$300 but it didnt fit where I needed it to go.

Thanks for the suggestions also...
