My 26 Experience
I probably shouldn't be considered a true liveaboard, as I'm not staying on the boat 7 days a week. But I live about 80 miles from my boat, which is conveniently about 3 blocks from my current client. Rather than driving back and forth every day, I spend several nights a week on the boat. Marina has good shower facilities, a deli, and there are several decent restaurants in walking distance. Eating out of a cooler has its disadvantages, but not enough to push me to get a small mini-fridge. Shore power helps run gadgets, mainly my laptop. Could I stay on the boat for longer stretches, certainly by myself. Could I spend a summer trailering up the coast, living aboard, you bet. But when company shows up, it gets crowded quickly. Not sure if this helps or not, just my 2cents.T J
