You will want to stop the houseboat out in the lake where you have plenty of room to drift a little because it take a bit of time to pull the ski boat in, get someone in to drive it, and untie it from the tow rope. Then the houseboat can go in and beach and tie up. After the houseboat is all tied up then you can bring the ski boat in and tie up the the houseboat. At least that is how we always do it.
