Thanks for the good input folks.
Although the window units are simple, I dont want to surrender the internal space that you have Phil, or block walkways outside.
If I go with a split system I'll need a professional instal for the gassing. On reflection, if I am going to go with AC then I ought to do it properly. I can probably put the compressor in a similar location to Daryl's. But getting copper tubes from there to salon or main stateroom would be a challenge. The flexible propane
line was bad enough to do.
I had been googling a bit and had looked at the Dometic material, but thanks for your links Gord. I am a bit tempted by the aircooled DuraSea rooftop unit. I have to check dimensions to see if it can fit the pilothouse hatch
. It would be sandwiched between a couple of raised solar panels
, and aesthetics would be tolerable.
But the other option is to get some solar
or 12v slow turning large diameter fans, mount them in both my hatch
openings in a ply structure the will keep rain out. If I can locate the fans without too much trouble I'll try this first.
There were still traces of mold
on the boat when I bought it. Clearly there had been a major issue, and a huge cleanup to be able to put the boat up for sale
. I found some traces in hard-to-get-to spots during my refit. The refit had us working on everything from stem to stern, and i doubt that there would be more than a few square inches that has not been scrubbed with Chlorox. But remnant spores might remain, and I do not want a re-occurrence. That stuff can kill you.
I will see how I manage living, and particularly sleeping, in these warmer months when I am aboard. Selling my house at present also, so cant use the boat as often as I would like just yet. Most long term residents in Queensland, myself included, only use AC as a last resort for periods of extreme heat. Such as now. 'Highest on record' temps have been occurring recently, could be Brisbane's turn today. I'm going up to the boat now for a bit to see how much of a hotbox it has become with a few days of high temp.
