I was bored and started to play around with boats. The first thing I built was a Horizontal Boat Storage. Here are some pictures. http://imgur.com/XVKA2http://imgur.com/4rHqV
You hit the button and the boats cycle through.
I also made a very simple Boat Station. http://imgur.com/7AgJhhttp://imgur.com/CEnB1
If you pull the lever you will only go through the first to stops. It is possible to set more locations and you can space out the stops.
