I live on a houseboat which is a boat that's been changed to be used primarily as a home.
Wow that's really cool! What are they like?
It is pretty cool. Most houseboats aren't motorized so they usually just stay still at a fixed point on dock but it is still shaky at times.
So there are some that are motorized then?
Yes, based on what people prefer, houseboats are still capable of operation from power. 
That would make sense, otherwise it might as well not even be a boat you know?
That's true. I know that there is even a community of fishing and houseboats on the southern side of Hong Kong Island which is also known as Aberdeen floating village. I would like to go there one day.
