Driving a boat is the easy part...understanding it's systems and limitations...well some people NEVER figure out their boats....
This is where "Less is MORE"
Not having complex costly gear to constantly maintain , reduces ones lifestyle only a tiny amount.
EG refrigeration on board under way is usually a $6K noisemaker , and a $$$ fridge to feed., plus big batteries to replace.
For $400 a large well insulated ice chest can be purchased.
Lasts a week (with no kids aboard) , how long are you unable to get to a dock?
KISS , the lifestyle for folks that enjoy the trip, not the tool box.
