When it (occasionally) seems like a good idea to try to explain to non-boaters explain why my boat takes a lot of time -- not to mention money -- to "maintain" it's systems, I tell folks to imagine living in their land home with THEM providing ALL of the utilities that on land a city or county or utility does for them.
At home our city sees that water is piped in reliably, sewage is piped away reliably, utility companies make sure that all phone and 'net access is maintained, and the electric utility makes darned sure that we have reliable surge-free power 24/7.
Often this makes "the light go on" in their imagination.
All that difference plus no economies of scale
... like my boat's refrigeration installation that cost about a thou and my labor took a week. For all that $ and labor-$-equivalent at home I could have one of the finer fancy fridges on the market! Compare all that luxury to a boat fridge with under 4 cubic feet.
That thousand $ range on the boat with the little oven? For about the same $ the house gets a countertop range and a wall oven.
And, so it goes.
When we pull up in our driveway and open the garage door with a click and turn on lights with another click, MUCH is taken for granted compared to living on our Floating Vacation Home
Love the boat. Love the "sailing life"... but there are compromises...
