I live on a 37 Fairliner with an aft state room, full head with shower. I have an entertainment center where the forward head used to be and a forward birth. The main salon has an appartment sized refer, 3 burner stove and microwave. A counter top with blender, toaster, coffee maker and wine wrack. Where you gonna put that on a 25 foot sailboat??
Been to Rock Port Tx. Nice town. Small like a 25 footer.
You better have a toilet and shower at the end of the dock or things are gonna get messy real quick. A nice resturant nearby too. Try living in your car for a week and see how you fare. I''ts gonna be pretty much the same.
