small compressor installed on a boat?

[bradlw]

One of my never-gonna-happen pipedreams is to
retire
sell it all
buy a liveaboard boat
and explore

a random thought pops into my head this morning about my pipedream on a liveaboard
I would ideally need a small compressor onboard. It wouldn't need to be a fast fill.

A long time ago I was certified as a nitrox and trimix blender, but I never really got into the weeds of maintaining and operating the compressor. I just remember it being a rather high-maintenance thing.... service intervals, filters, etc... but I never got into the weeds of it

so crude ballpark cost for a small compressor for that sort of application?
and what sort of ongoing maintenance/service is required for such a thing?

Bauer Mariner, around 10k.

An issue is having the power overhead.

how practical are they for an occasional fill? A lot of maintenance or consubables needed?

<$2 per fill if you dive 100 tanks a year. Service is rare but parts are costly.
Or you can buy a unit which is cheap with cheap parts and be constantly replacing the parts or entire unit.

A gas powered Junior would be 30+% less and work fine for a few tanks a month.
