Air Conditioner BTU recommendations, please

I have the slightly larger 07 260da with factory 7k btu and we boat in N.J.

my observation is that the unit doesn’t keep up on the 90++ days when the sun is out. Set at 70 and it runs 73-75 in the late afternoon in our mid 80s bay. usually hits set point within an hour Of sunset.

definitely working properly, had a cruiseaire dealer service it. Heat is excellent even with water in the middle 40s. Really does great with humidity control by not short cycling. Even when the temp is higher because it can’t keep up it’s comfortable from the dehumidification.

in Rhode Island I might favor the 6k,particularly if the water was cooler. Should be more efficient in cooler water

Thank you.

Looking to see if anyone has any experience with the MABRU Power Systems AC Units. Couple of threads without any detail. Original on my 340DA was a CruiseAir 12k that lasted quite sometime with a compressor failure. Replaced it with another CruiseAir 12k that lasted for 14 months with a compressor failure. Of course out of warranty. Since I live in the Carolinas off the coast the unit was running in the summer months constantly. So I decided to replace it with a Dometic 16k. Worked fine for the past 4 years but I have a freon (410A) leak that cannot be repaired. Considering the MABRU but not much info other than on You Tube. Cost for MABRU is about $1k more than a Dometic drop-in. Looking for a similar footprint since there are limitations for mounting under the V-berth with the plenum adapter.

Look into Webasto or Mermaid. We have both and are very happy with them. I do think the Webasto is a little quieter and puts out colder and hotter air.
