Well, part of the reason we would like to build instead of buy, is that we really want to "know" our boat. I also think that the excitement of knowing that your own hard work
and sweat helped to create something that you can live on, and travel on is the kind of reward that can't be bought or pre-fab. Certainly, it isn't the cost, as decidedly it can end up being far more expensive than planned. I also like the control and options you have for every aspect of the boat.
