You bring up a good point. Most land people don't understand that a live aboard boat is somebody's home. To the majority, a boat is a place to spend a day out "boating" to have fun.
Personally, TA, I understand your need for security completely. I hope to be joining you in living aboard in the very near future (not with you personally, though I am single
) and I am always aware that boats are no where as secure as a home or even the average car. I try not to dwell on that too much
