we looked seriously at adding a compressor to our 42', but even with what most consider a lot of space...we could not mount any where that would make sense except outside ahead of the mast. That would mean leaving an expensive Bauer unit out in the weather for all practical purposes and that would mean even more maintenance.
We then looked at some custom, an engine driven system, and some hybrids and if money were no object they may be an option. Even the Bauer is near $10K with filters and spares, and would still take a while to fill 2 or 3 cylinders.
Engine driven would be an issue with our Yanmar for both space and engine load. Electric almost out of the question unless you are running a stout gennie and the compressor at the same time = a LOT of noise. We have a 6K gennie and that is not enough to run the low end units. Upgrade to +++KW is another chunk of change.
Small system would work but take hours to fill two tanks... I have seen a lot of used dive compressors in the last year or two both commercial as well as gov't surplus at great prices. But when you factor spares, installation and look at the hours on the used gear it just did not work for us.
You buy dive compressors cheaply if you go off brand, foreign made, less quality air systems, but for something that your life would depend on, we stayed with name brand quality.
We have taken the course of buy two tanks this year, to go with the four we have and add a couple more later on. We think this will be the best compromise.
