The Get-together and the Boat Exit

I vaguely remember being at a house party with my husband. Maybe I'll remember more later. When we left the party we were going to take a ship or large boat home instead of a car, I could see them from the window of the apartment which was on the second floor. It ended up with my husband driving us down the highway in a small boat. I didn't know how he steered it, I just remember that he managed somehow to keep us in our lane. In our boat. On the highway.
