I cruised and lived aboard for about 3 - 4 years in various situations from active offshore
sailing, coastal cruising, live aboard
in a marina and island hopping in the tropics. That was 15 years ago so things have changed.
At the time, and this may still apply... I missed access to live "high art/culture". As I age I enjoy seeing live performance of opera, ballet, plays, concerts, museums, and other perfomance. These things are less accessible except if you are parked close to a major metro area cultural center.
I certainly don't care about clothes, so there's not much to miss there.
I found I met more people and had more social interactions, although they were mostly other sailors... so it was a narrower range of people.
I did miss the convenience of personal transportation, regardless of where I was. I supposed I was spoiled in being able to go where I want when I want without hassle. Public transport is great in urban areas and so this is not an issue. But that kinda limits cruising. Bikes are easier as a land based person than a live aboard
cruiser. Bikes are good for all sorts of reasons.
is more a hassle on boats, so I miss the convenience that land base live offers. But with less laundry
this becomes less of a problem.
Don't watch much TV, but am addicted the internet
for information. I would need that on some level, it wasn't mature when I was living aboard
so I didn't miss it.
Love to get rid of all the junk we accumulate... so living aboard
solves that one nicely. Most of my "art" is small and can be sent off to others to enjoy.
With the advent of digital media there's no need to miss music, movies and so forth. Now you can take it all with you.
I like the self sufficiency of living aboard... which mimics owning a home. I lived in rental apartments, lofts and so forth so moving aboard meets that need.
I miss food
options as I get bored with the same cuisine all the time... and this includes restaurants as well as marketing
, produce etc.
