We found that most move back ashore due to "un-realistic" expectations.
When you expect warm, sunny days - it still rains
Many people can not handle sitting, reading, learning, watching as an activity
When you expect the marina to put down ice-melt, or change light bulbs - and doesn't
You don't realize that the "motion and noise" of the boat NEVER stops
Cramped space or uncomfortable spaces are unforgiving and don't get better.
Life still goes on, and the boat can be an asset or a liability, all depends on your point of view.
However, we love the motion. We are fixing the heating systems, water systems, and have 4 hatches to seal this spring. The view is awesome. We really like each other but still respect the need for privacy or alone time. All the rest is just - life!
Expectations - plain and simple. That being said, there is nothing more miserable than not enjoying your life, ashore or aboard...so make the change!
