Nanatorium, Me and 2 other people I know had the same problem. I started up a new game, and the Scott family does have a houseboat. It disappeared along with another houseboat (it's called the Happy Houseboat and I tried moving my sim in it and it put her in the middle of the ocean). My Scott family also was in the middle of the ocean. I put them in a new house. Both of those houseboats disappeared.
