Apparently we have been looking in the wrong places.

I came across this because I have been looking at using a mini-split ac system to utilize their inverter driven compressors. Although I would swap the air cooled coil for a water cooled coaxial one...

Something tells me it needs shorepower for startup, and every time the compressor kicks in

That would wreck the heating ability in cold weather as most mini splits use a reverse cycle phase to melt ice on the unit when condensation freezes.

AS they are 300% to 50% more efficient than a heating wire , why loose a huge advantage?

Easier to cool as it would probably be in the shade ?

Yeah, those numbers don't really add up to anything practical. You'd almost have to design the boat from scratch, specifically for maximum solar power and well-shaded, insulated interiors. Which wouldn't be a bad idea, just not something I could use in my 1980 trawler.
