Facing the same question: boat is virtually cruising ready and we were meant to cast off September this year...... but my wife stepped into this new business venture three years ago, which I am happy to say, is working out very well.
So, it looks like I will leave September 2017 now and she will fly in where ever she can for the next 2 years. But, also I will probably build in 2 or 3 months breaks (i.e. in storm/hurricane seasons), to come home and see the family
, daughters, grandson, etc. So that way we can bridge the time till my wife can actually come and live on the boat.
I have a friend who is doing it this way and it seems to work quite well like that.
