We do not currently live aboard but have done so and do spend weeks away from shore power at a time.
We have a 1/2HP unit with belt driven reciprocating compressor and pumped sea water cooled condensor on a 40 foot sail boat. Box has eutectic filled (just alcohol and water mix in our case) tanks for holdover. Kills around 150 odd liters (never measured it) of unfrozen stuff down to -18C very quickly and once done so runs at most an hour per day (say 45 Amp hours /day) to hold it down/freeze fish etc added - that with it running inefficiently at low pressure with high condensor cold sea water cooling flow, as we leave the flow set up for high water temperatures. It will hold over for several days if necessary (of course, a function of holdover tank size and insulation).
Refrigeration is done seperately with a thermoelectric unit which we like (it is properly sized with care taken with the ventilation of the heat sinks) and uses around 30 Amp hour /day if not stocked with frozen fluids ex the freezer.
The boat was built for us and as was to be used for extended periods on board we tended to put comfort ahead of energy use where we felt necessary. If ever did another custom build for myself would do the same type of installation again.
