I love being on the water and especially on a houseboat!  There is nothing like falling asleep on the water! That must be really nice. It is important to not mistake a houseboat for a boathouse, which is actually a shet used to store boats. Have you ever seen a boathouse? I have not. Can you tell me more about houseboats ? Sure. Did you know that there are some houseboats that are not motorized? Those are actually moored and kept at a stationary point I didn't know that.  I assumed all houseboats moved.  When did houseboat come into popularity?
